Heat Capacitive Active Mirror Design for Thermal-Lens-Free Solid State Laser
演讲课题：Heat Capacitive Active Mirror Design for Thermal-Lens-Free Solid State Laser
Thermal-lens issue is the most serious defect of solid state lasers even in the case of thin disk geometry. I propose a concept change high efficiency cooling to uniform thermal-induced phase shift over the full aperture of a disk laser. HCAM technique composed of a bottom cooling area control and a thin ring heater control for fine tuning. HCAM design decreases the thermal phase shift two to three orders of magnitude smaller over a wide range of disk thickness. We investigated the second HCAM effect in the top cap volume of a thin disk laser.
