Compact 7.8-W 1-GHz-Repetition-Rate Passively Mode-Locked TEMoo Nd:YVO4 Laser Under 880 nm Diode Direct-in-Band Pumping
We demonstrate a compact high-power passively mode-locked TEM00 Nd:YVO4 laser with 1 GHz repetition rate by 880 nm diode direct-in-band pumping. At the absorbed pump power of 19.9 W, a stable mode-locked output power of 7.8 W was obtained with the pulse width of 21.4 ps and a beam quality factor of M2 < 1.5, corresponding to an optical-optical conversion efficiency of 39.2%.
