HIGHLY RELIABLE LASER DIODE SYSTEMS OF HIGH POWER AND HIGH BRIGHTNESS BLUE GLOW AND METHODS OF THEIR MANUFACTURE Russian patent published in 2024 - IPC H01S5/06 H01S3/30 B23K26/21 

FIELD: laser systems.

SUBSTANCE: group of inventions relates to the laser systems of high power and high brightness, providing a blue laser beam. The solid-state device and the optical module are located in the internal cavity of the casing. The laser beam has a wavelength of 410 to 500 nm and a power density of at least 0.5 MW/cm² at the propagation surface. Upon exiting the housing propagation surface, the beam has a power of at least 100 W and a beam parameter product (BPP) of less than 100 mm⋅mrad. The inner cavity of the housing contains oxygen and is free from sources of silicon-based contaminants, which prevents the formation and build-up of SiO₂, with a degradation rate of beam properties of 2.3% per 1000 hours or less.

EFFECT: invention ensures preservation of the initial properties of the beam, including the power level.
