Tm:YLF

Regular price $550.00

Tax included.

Thulium doped yttrium fluoride lithium (Tm: YLF) crystal possesses the advantage of low nonlinear thermo optic constant, refractive index as well as high beam quality output. Due to such advantage of Tm: YLF, it is widely used in the fields of scientific research, education, production and other optoelectronic fields. The pump wavelength of Tm: YLF crystal is 792 nm, and the output wavelength is 1900 nm of the linear polarized laser.
