研究目的
To demonstrate a dual-wavelength continuous-wave laser with direct intra-cavity pumping using a 879 nm laser diode that utilizes Nd:GdVO4 and Nd:YVO4 crystals, eliminating the gain competition between the 912 nm and 1064 nm transitions for the first time.
研究成果
An efficient intra-cavity pumped dual-wavelength laser based on a 912 nm quasi-three-level and 1064 nm four-level laser with Nd:GdVO4 and Nd:YVO4 crystals was successfully developed, effectively eliminating gain competition between the 912 nm and 1064 nm transitions.
研究不足
The experimental results are influenced by many factors, and the theoretical value represents the simulation result under idealized conditions. The output power of the four-level laser increased faster than that of the quasi-three-level laser due to the large gain of the former.
