Preparation of power laser single crystal slabs based on ytterbium-doped garnet aluminates with ASE suppression

摘要

ufeffpu0159u00edprava performance laser monocrystal slabs at least 70 mm diameter active environment based on single crystal ytterbiem (aluminu00e1tu016f grenade in the bud by grown in the melt in the reducing atmosphere under the cap, where reducing atm osfu00e9ra over taveninou (10) in tavnu00e9m cup (1) contains during the melting of at least 30% hydrogen.subsequently evacuated and melt (10) is homogenized, and stripped of dissolved gases mixing wire (7), and after this process, vacuum is again replaced by reducing atmosphere for the initiation of the growing crystal on the bud, and after reaching the desired size of the monok rystalu this further processed to product for the production of laser slabs.which is temperovu00e1n at high temperature in a protective atmosphere to eliminate the displacement and conversion of active laser ions and subsequently provided with absorbent layer for suppressing the phenomenon of amplified spontaneous emission and optical interfaces of this absorption layer with laseruju00edc the parts of the monokrystalu is indistinguishable from the point of view of the refractive index and material thermal expansion.the described equipment for preparing performance laser monocrystal slabs.
