Astigmatic diode beam end-pumped Nd:YAG laser

  • Received Date: 1992-01-21
  • The Nd:YAG laser end-pumped by astigmatic diode beam is reported,for the purpose of studying diode pumped solid-state laser array. With astigmatic beam pumping, TEMn0 mode and TEM0m oscillations have been achieved, respectively, by meridianal focal plane pumping and sagittal focal plane pumping, The TEMn0 mode laser has the minium threshold of 385mW, CW output power of 320mW with 28% slope efficiency, and stable 232mW CW output power with 20% slope efficiency. The CW output stability is also described.

Abstract: The Nd:YAG laser end-pumped by astigmatic diode beam is reported,for the purpose of studying diode pumped solid-state laser array. With astigmatic beam pumping, TEMn0 mode and TEM0m oscillations have been achieved, respectively, by meridianal focal plane pumping and sagittal focal plane pumping, The TEMn0 mode laser has the minium threshold of 385mW, CW output power of 320mW with 28% slope efficiency, and stable 232mW CW output power with 20% slope efficiency. The CW output stability is also described.
