High-power 1064-nm LD array cluster side-pump YAG solid state laser

The theory of side pumping Nd:YAG solid state laser by high-power array-semiconductor laser cluster are discussed. On the basis ofthat, we design, construct, debugging and survey the performance ofthe laser. The solid state laser device has the following technical specifications: It adopts 3 rank and 3 line, add up to 9 continuous output LD of 20W and 808nm. Nd:YAG laser bar is ?3mm, output wavelength is 1064nm, highest output power is 52.3W, output light mode is continuous multimode, the opto-opto conversion efficiency is 29%.
