In the past thirty years, high power laser technology has been dominated by Nd:YAG as the gain medium. The pump wavelength of Nd:YAG is 808nm, and the lasing wavelength is 1064nm. It is categorized as four-level laser. The pump wavelength of Yb:YAG is 940nm, and the lasing wavelength is 1030nm. It falls into quasi-three-level laser category. Because Yb:YAG have higher quantum efficiency and less surplus heat, it have the potential to replace Nd:YAG.
The purpose of this study is to develop a multi-reentrant two-mirror Yb:YAG ring laser. In this thesis, we will introduce multi-reentrant two-mirror ring laser. The thermal problem of quasi-three-level laser was overcome by multi-wavelength coating on gain medium and input/output couplers, numerical simulation for mode match, and efficient TE-cooling for laser crystal.
This symmetrical two-mirror figure ¡§8¡¨ ring cavity has the merit of compact, few optical elements, and easy design. The 1030nm output laser of our ring cavity promises to make the design widely applicable to solid-state lasers, such as single longitudinal lasers and mode-locked lasers.
