Abstract
The continuous-wave (CW) single-frequency single end-pumped 1064 nm laser with maximum output power of 9 W was experimentally demonstrated. An a-cut Nd:YVO4 crystal was end-pumped by a fiber-coupled laser diode (FCLD) at 808 nm. The four-mirror bow-tie ring cavity with a Faraday rotator and a half wave plate was applied to eliminate the spatial hole-burning effect. A solid etalon was inserted into the cavity to obtain the single-frequency output with M2 ≈ 1.14. The maximum output power was 9 W and the optical-optical efficiency was 36.6% with 24.6 W of the incident power. The fluctuation of frequency was about 200 MHz.
