    Tm YLF Crystals For Many Applications In Scientific Defence Medical Fields

    Tm:YLF

    Two-micron Tm3+ lasers are of interest for many applications in the scientific, defence, and medical fields. Thulium readily substitutes into many crystal hosts that are suitable for high-average-power laser systems and it has an absorption band at ~0.8 m allowing excitation with commercially available high power laser diodes. Thulium doped yttrium fluoride lithium crystals have low nonlinear refractive index and thermo optic constant , which are very suitable for the application in the fields of scientific research, production, education and other optoelectronic fields. The crystal is a negative uniaxial crystal with a negative refractive index temperature coefficient, which can offset some thermal distortion and thus has high beam quality output. The pump wavelength is 792 nm, and the linear polarized laser with wavelength of 1900nm outputs at in the direction of a axis. outputting light from c axis is non-linear polarized. High power laser output can be obtained by selecting proper crystal size and doping concentration.
