Analysis of Thermal Effect in Thin Disk Laser: A Review

Abstract

Since its first invitation in 1993, solid-state diode end-pumped thin-disk laser attracts much attention due to its significant improvements in the solid-state laser system. It had many advantages; it has high optical and electrical efficiency, high produced peak power, a simple cooling system, and high beam quality more than the usual solid-state diode laser system. The thin-disk laser (TDL) permits an effective pulse mode, which permits a new type of very short-pulsed laser system that could be used in the industry. Due to the influence of the many factors such as effective cooling system, the type of pumping, and the used thin crystal, a one-dimensional heat flow through thin-disk laser could be achieved which permits excellent enhancement in the beam quality. Finally, in this work, a review is made to the works devoted to discussing the basic principle and the solutions used to analyze the thermal effect in the thin disk laser.
