The mirror in the HR1015-AG is premounted in a Ø1" unthreaded aluminum housing and can be mounted into Ø1" optical mounts or a threaded SM1 (1.035"-40) lens tube with the use of SM1RR retaining rings. This tab compares four of Thorlabs' coatings for the Ti:Sapphire wavelength range: our low-GDD dielectric coating for 700 - 930 nm, our ultrafast-enhanced silver coating, our standard protected silver coating, and our broadband dielectric -E02 coating. Very interested in how this mirror (and your other coatings) effects polarization. Upon request, we can provide individual test information and a testing certificate. This book contains everything you need to know to measure even the shortest, weakest, or most complex ultrashort laser pulses. Cheers. 29, 517 (1998). 1-7 of 7 results. Response from Javier at Thorlabs to matthias.raunhardt: The damage threshold is mainly dictated by the peak power of the laser used. Custom optic sizes, geometries, substrate materials, and coatings are available with prices on modified stock that are comparable to our stock offerings. When working with silver mirrors, follow standard practices for handling optics. Protected Silver Mirrors. The damage threshold is then assigned to be the highest power/energy that the optic can withstand without causing damage. For more information on cleaning optics, please see our Optics Cleaning tutorial. Protected Silver … A good rule of thumb is that the damage threshold has a linear relationship with wavelength such that as you move to shorter wavelengths, the damage threshold decreases (i.e., a LIDT of 10 W/cm at 1310 nm scales to 5 W/cm at 655 nm): While this rule of thumb provides a general trend, it is not a quantitative analysis of LIDT vs wavelength. Pulsed lasers often do not heat the optic enough to damage it; instead, pulsed lasers produce strong electric fields capable of inducing dielectric breakdown in the material. Optical Mirrors are … The overcoat on these mirrors allows them to perform better than our unprotected gold mirrors in the mid-infrared (MIR), while Compared to our low-GDD dielectric mirrors for 700 - 930 nm, this enhanced silver mirror offers similar GDD, a slightly wider reflectance range, and a slightly lower reflectance value. Found inside – Page 48Mirrors polarization performance The mirrors themselves will also contribute to polarization issues because mirror ... poor for all mirror types measured—a New-Focus 5102 NIR broadband dielectric, a ThorLabs protected silver mirror, ...

A dichroic mirror separated the light coming from the sample (green and red portion of light spectra) onto two cameras. hello, Thank you for contacting Thorlabs. Made in USA Price Enter your price range below. Economy Front Surface Mirrors. In this regime, the LIDT given as a linear power density can be applied to any beam diameter; one does not need to compute an adjusted LIDT to adjust for changes in spot size, as demonstrated by the graph to the right. Pulsed Nanosecond Laser Example: Scaling for Different WavelengthsSuppose that a pulsed laser system emits 10 ns pulses at 2.5 Hz, each with 100 mJ of energy at 1064 nm in a 16 mm diameter beam (1/e2) that must be attenuated with a neutral density filter. The enhanced silver coatings can be used at normal incidence but there will be a slight shift in the GDD as well as the reflectivity of the -AG coating. Unfortunately, it can be very difficult to compare the LIDT specification of an optic to your laser. Optical Mirror by Thorlabs Inc | Visit website. Concave Mirror Selection Guide. Pulsed lasers with high pulse repetition frequencies (PRF) may behave similarly to CW beams. While the test results are only representative of one coating run, Thorlabs specifies damage threshold values that account for coating variances. As a result, both CW and pulsed LIDT values must be compared to the properties of the laser system to ensure safe operation. It would also be nice to have plots from a couple of different lots provided on the Graphs tab to show the variability of the reflectivity. These LIDT values are not valid for ultrashort pulses less than one nanosecond in duration. These lower thresholds are due to absorption or scattering in the cement or metal coating. The damage analysis will be carried out on a similar optic (customer's optic will not be damaged). From optomechanical components to telecom test instrumentation, Thorlabs' extensive … If this relatively long-pulse laser emits a Gaussian 12.7 mm diameter beam (1/e2) at 980 nm, then the resulting output has a linear power density of 5.9 W/cm and an energy density of 1.2 x 10-4 J/cm2 per pulse. Bevel. If the optic was tested at a wavelength other than your operating wavelength, the damage threshold must be scaled appropriately. These lower thresholds are due to absorption or scattering in the cement or metal coating. At this point you can employ the drop and drag method or applicator method as detailed in our Optics Cleaning Tutorial at http://www.thorlabs.com/tutorials.cfm?tabID=26066. If the optic was tested at a wavelength other than your operating wavelength, the damage threshold must be scaled appropriately [3]. Note: Your Quotation Request will be directed to Thorlabs Inc . Found inside – Page 548The light beam is reflected by the mirror (BB1-E02, Thorlabs) with an incident angle of 45 ° towards the cylindrical ... of hollow silver coated glass beads (diameter 515 μm, Cospheric LLC, density 1,08 g/cm3) are added to get a ... Do you have any data on the transmission of light through the silver coated mirrors? Each mirror is coated to 0.05 mm of its straight edge and has had a wedge of substrate removed to facilitate the pickoff of one beam without clipping the other. Best regards, We have a lot of these mirrors, but Im concerned that the wavelength-dependent phase shift affects our ultrafast laser pulses centered at 800nm. GVS012/M - 2D Large Beam (10 mm) Diameter Galvo System, Silver-Coated Mirrors, Metric, PSU Not Included : Zoom.

Pulsed lasers, on the other hand, often strip electrons from the lattice structure of an optic before causing thermal damage. for both p and s polarization? This 25.4 mm (1.0 inch) diameter mirror is made from a 6.0 mm thick Borofloat® 33 substrate which is coated with the ER.2 silver coating. The longer the pulse duration, the more energy the optic can handle. For reference, a Gaussian beam typically has a maximum power density that is twice that of the uniform beam (see lower right). Additionally, for highly transparent materials, there is little to no drop in the LIDT with increasing PRF. Please keep in mind that these tests are performed on clean optics, as dirt and contamination can significantly lower the damage threshold of a component. The Ø1/2", Ø1", and Ø2" round silver mirrors are also available in packs of 10 at a discount over the individual price. Thorlabs - ME1-P01 Ø1" Protected Silver Mirror, 3.2 mm Thick Products Home / Optical Elements / Optical Mirrors / Plano Metallic Mirrors / Round Protected … The calculation above assumes a uniform beam intensity profile. Found inside – Page 92It consisted of a convex, 2m radius of curvature (ROC) followed by a concave, 4m ROC silver mirror (Eksma Optics). Doubling the beam size was ... The plate was software-controlled via a motorised rotation stage (PRM1Z8, Thorlabs). When an optic is damaged by a continuous wave (CW) laser, it is usually due to the melting of the surface as a result of absorbing the laser's energy or damage to the optical coating (antireflection) [1]. ... λ/10 First Surface Mirrors are ideal for demanding beam steering and reflection … Designed to reflect light that is externally incident on the hypotenuse of the prisms, these hollow roof prism mirrors are ideal for use as a retroreflector in applications where refraction, chromatic aberrations, material absorption, or front surface reflections from standard prisms are undesirable. I would like to ask if you have information on how the protected silver mirrors(especially For the UV to NIR range we measure our mirrors with the perkin Elmer lambda 950 spectrophotometer, this is used from 190nm-2600nm. Note that the guideline presented here assumes room temperature operation and optics in new condition (i.e., within scratch-dig spec, surface free of contamination, etc.). I can reach out to you with other typical data we have collected at angles of incidence other than the design 45 degrees. For beams sizes greater than 5 mm, the LIDT (J/cm2) will not scale independently of beam diameter due to the larger size beam exposing more defects. The LIDT for an optic greatly depends on the type of laser you are using. Elliptical Mirrors: Applications in microscopy discusses the importance of the elliptical mirror; the third solution after parabolic reflectors and lenses for which apodization factors were established in 1921 and 1959 respectively.
