超寬帶介質膜反射鏡是歐洲進口的超高性能的介質膜激光反射鏡，可實現350-100nm波段范圍內平均高反射率，入射角度可達0-50度。最大的GDD群延遲色散為350fs2,不會導致脈沖展寬。超寬帶介質膜反射鏡成為傳統激光反射鏡的**替代產品，特別適合Nd:YAG激光及其各種倍頻波長使用。

Ultra-Broadband Dielectric Mirrors perform high reflection in whole range of 350 nm - 1100 nm and show high average reflection in very wide range of angle of incidence (0°-50°). As maximum GDD reaches about 350 fs2, mirrors do not cause considerable pulse broadening for 1 ps and shorter pulses*. Due to these features ultra-broadband mirror is a good choice to replace three or more convetional laser line mirrors, especially designed for Nd:YAG and its harmonics.

* specific GDD values are indicated in GDD vs. Wavelength curves

	High reflection in ultra broad wavelength range
	Wide range of acceptable ange of incidence
	High laser induced damage threshold
	Could replace several conventional components
