Title: Thermal control of pumped laser cooling system - uses combined cooling and insulation to prevent lens-forming in medium
Inventor: KUBA KAZUKI
IPC: H01S3/05
Filed: 1990-10-12
Abstract: The light activated lasing medium (1) is contained in a vessel of rectangular section its sidewalls bounded by transparent cooling channels (5) and insulated at the edges from external heating (20,30) with additional cooling. Energy is absorbed from the pumplights (7) causing density changes in the medium thus affecting the lasing stability. These effects are minimised by choice of the insulating material, the additional cooling and by reflective coatings so that heat is uniformly transmitted and teh formation of refractive lenses in the medium is minimised. ADVANTAGE - Precise control of thermal gradients in laser medium.
