| Abstract: | A highly efficient 880-nm diode-pumped actively Q-switched eye-safe laser at 1525 nm with a double-ended diffusion-bonded
YVO4–Nd:YVO4–YVO4 crystal as the self-Raman medium is demonstrated. As high as 19.2% diode-to-Stokes optical conversion efficiency is obtained
with an absorbed pump power of 5.2 W at a pulse repetition rate of 20 kHz. |
