LASER Russian patent published in 2003 - IPC

FIELD: laser engineering. SUBSTANCE: proposed solid-state pulsed periodic solid-coolant laser has cavity accommodating reflector with active element mounted in optically transparent holder and pump lamp. Pump lamp is covered on entire length of discharge gap on active element side with diffusely deflecting coating. The latter is made in the form of longitudinal strip whose width makes up 30-35% of pump-lamp bulb outer diameter. Silicate base zinc included in coating composition has reflection factor of minimum 0.85 at wavelengths ranging from 0.5 to 0.9 mcm. EFFECT: enhanced stability of directivity pattern and radiation energy. 4 dwg
