摘要
We present the development of a high-power laser source operating at 532 nm produced by frequency doubling a Yb-doped fiber amplifier. The fiber amplifier has a multistage design, and uses large mode area Yb-doped fibers as the gain medium to produce > 2 kW of laser power at 1064 nm. The amplifier design is optimized to reduce non-linear effects, and operates at linewidths as narrow as 45 GHz. By focusing the fiber amplifier output into an LBO crystal, more than 1 kW of 532 nm light is produced. Single pass conversion efficiencies as high as 54% are achieved providing a unique combination of high power and high quality 532 nm laser source. The 532 nm laser is fiber coupled, making it an ideal source for industrial applications.
