Features

High Damage Threshold

Meticulous production procedures guarantee these mirrors will withstand 45 J/cmfluences at 1064 nm for the 10QM20HM.10 and 10QM20HM.15 mirrors. Their coatings are highly durable and will withstand repeated cleaning. Our HE.1 and HE.2 coatings can withstand as high as 40 J/cm2 at 1064 nm and 10 J/cm2 at 532 nm energy fluences respectively.

Easy Product Selection

Select the proper mirror based on your current application. If the requirement is that a single optic be used for 0 to 45 degrees angle of incidence, then please choose 5104, 5105 or 5124. The coating on these mirrors allows for usage across the full 0 to 45° angle of incidence. However, choosing these mirrors sacrifices the higher damage threshold and scratch dig. If your fluence is higher, then you may want to consider the 10Q20HE.1 or 10Q20HE.2. An all dielectric coating for a single wavelength and single AOI is applied onto a fused silica substrate. This allows for higher damage threshold and better surface quality. But if you require the highest damage threshold, then please pick 10QM20HM.15 which boasts a damage threshold of up to 45 J/cm2. The 10QM20HM.xx parts are available for either 0 or 45° angle of incidence and at one or two inches in diameter. A last choice is if your application requires the mirror to reflect at two wavelengths. The selection here is the 10QM20HDM.10 or HDM.15 mirrors, which are optimized for both 532 and 1064 nm at a one inch diameter size.

Coatings for Nd:YAG Fundamental & Harmonic Wavelengths

We offer Nd:YAG mirrors for the fundamental 1064 nm, frequency-doubled 532 nm, frequency-tripled 354.7 nm, and frequency-quadrupled 266 nm laser lines at either 0° or 45° incidence angle. A dual-wavelength mirror for 1064 and 532 nm is also available. Reflectivity is greater than 99.7% for s-polarization and greater than 99% for p-polarization.

UV Fused Silica Substrates

Fused Silica is synthetic amorphous silicon dioxide of extremely high purity. This non-crystalline, colorless silica glass combines a low content of inclusions with high refractive index homogeneity, a very low thermal expansion coefficient, and excellent transmittance in the wavelength regime from UV to NIR. As a result, these mirrors will perform better with temperature fluctuations and is ideal for high-energy laser applications due to its high energy damage threshold. For more information, please see our Optical Materials technical note.

Borofloat® 33 Substrates

Borofloat 33 is a high quality borosilicate glass that offers low thermal expansion and high thermal shock resistance. Its material properties and moderate cost make Borofloat 33 an ideal substrate for general purpose applications. For more information, refer to the optical material technical note.
