We firstly investigate the characteristic of Yb:KGW crystal in the quasi-three-level laser system and the monolithic cavity design. We then explore the output performance and the temporal behavior of the monolithic laser. Optical vortex beam is further generated by a cylindrical lens mode convertor and the vortex structure is examined by a Mach-Zehnder interferometer. Finally, theoretical analysis is carried out to analyze the experimental results. Dual-comb self-mode-locked operation with abundance of transverse pattern along Nm- and Np-axis is experimentally obtained with high-power high-repetition-rate Yb:KGW monolithic laser. We further employ a cylindrical lens mode convertor to generate LG0,2 and LG0,3 mode and the vortex structure is successfully observed through a Mach-Zehnder interferometer. The simulation result corresponds well with the experimental result for the LG0,2 mode. Chen, Yong-Fu 陳永富 2018 學位論文 ; thesis 57 zh-TW |
