LZOS Company manufactures laser glass types in silicate and phosphate base compositions that are used for science, technology, medical and special laser systems fabrication.
Laser glass is broad varied in its properties. The basic laser glass parameters are presented in Table below.
silicate laser glass (GLC)
Silicate base glass types GLC1, GLC9 are specified by high energy and thermo mechanical parameters allowing them to be used for frequency technological laser creation.
Combination of great laser efficiency and high thermal resistance makes glass type LGC61 be a unique substitute of expensive laser crystals.
Silicate glass types GLC6, GLC7, GLC8 are related to athermal class that ensures minimal wavefront thermal aberrations arisen during active element pumping.
All glass types except GLC1, are able to be used without filter absorption of pumping radiation ultraviolet band.
phosphate laser glass (LFC)
Laser efficiency of phosphate glass is higher than silicate one. Phosphate glasses feature high gain, larger section of induced emission, more narrow lasing line, optical athermal characteristics and resistance to ultraviolet emission affect. However, glasses on phosphate basis have less mechanical and thermal strength than silicate ones.
LFC4 and LFC5 have low values of nonlinear coefficient of refractive index that is essential factor for high-power laser chains creation. Besides, LFC5 is distinguished by high heat resistance among phosphate glasses. LFC4 glass type is noted for high proportion of activating agent at low concentration quenching of luminescence that gives an opportunity to use it for compact pulse-periodic laser.
Active elements made of laser glasses are characterized by high optical homogeneity (DELTA nd=10-6 within wavelength to 1000 mm), low absorbance at lasing wave-length (1-2)10-3 cm-1 and no defects in forms of striae and large bubbles.
Glasses stability to laser radiation affection is defined by glass technology and depended upon active element performance conditions. Solid laser damage resistance of glasses molded in ceramic vessel levels to 20-40 J/cm2 at 40 nc of laser pulse duration and area of affection ~1cm2. Silicate and phosphate laser glasses molded in platinum melting pot have solid laser damage resistance within 10-15 J/cm2 under the similar operation conditions.
