High Reflection Coatings

*High reflectance for laser application
*High damage threshold

Single wavelength, high power HR coatings are suitable for intra and extra cavity use. They provide the ultimate high reflectance of Rs>99.8% and Rp>99% for a specific wavelength.

Type	Reflectance	Damage Threshold	Wavelength Covered(nm)
Single wavelength HR	Rs>99.8%,Rp>99%	10KW/cm2, 0.5ns～25ns	441.6, 488, 514.5,532, 632.8, 680

These Nd: YAG/YLF laser mirrors are designed for high reflectance at the appropriate dual wavelengths. They are intended for external use at either 45° or normal incidence. We also offer dual wavelength mirrors for use at the fundamental and second harmonic wavelengths as well as a selection which will reflect a Hene or diode laser guide beam as well as the fundamental wavelength.

Type	Reflectance	Damage Threshold	Wavelength Covered(nm)
Dual-wavelength HR	R>99% / R>99.5%	3J/cm2, 10ns	351/1053
	R>99.5%/R>99.5%	3J/cm2, 10ns	532/1064
	R>99.5%/R>99.5%	3J/cm2, 10ns	632.8/1064

Broadband coatings are offered for the major telecom bands and these provide over 99% average reflectance over a wavelength range from 1310 to 1550nm.
