Micro crystal laser cooling appts. - uses sapphire or synthetic diamond plane ground as conductor of thermal energy and is in contact with micro crystal surface

摘要

The micro crystal solid state laser has the monolithic crystal (3) located in an aperture within a metallic plate (4). For cooling purposes, a sapphire or synthetic diamond is plane ground and is in contact with the surface of the crystal. The surfaces of the sapphire or diamond are highly polished and provide a high thermal conductivity and optical transparency. The sapphire or diamond is in contact with the metal plate that acts as a heat sink. ADVANTAGE - Even thermal dissipation, low temperature gradient, high efficiency.
