METHOD FOR CREATION OF COMPOSITE LASER ELEMENT BASED ON OXIDE CRYSTALS Russian patent published in 2021 - IPC H01S3/06 

FIELD: laser technology.

SUBSTANCE: invention can be used for creation of a composite laser element based on oxide crystals. The soldering is carried out using glass containing oxides of lead PbO, boron B₂O₃, aluminum Al₂O₃ and silicon SiO₂. Before soldering, glass is surfaced at a temperature of 530-620°C on the contacting surfaces, followed by cooling to connect the crystals into a composite laser element. The soldering is carried out at a temperature of 550-700°C, a specific pressure of 15-40 kg/cm², for 10-45 minutes. The glass additionally contains zinc oxide ZnO at the following component ratio, wt.%: PbO - 61.5-64.3; B₂O₃ - 19.4-17.3; SiO₂ - 5.8-7.4; Al₂O₃ - 7,05-5,5; ZnO - 5,95-5,05.

EFFECT: reduction of the soldering temperature of the composite active element in the air atmosphere.
