Compact high repetition-rate actively Q-switched and mode-locked eye-safe Nd:KLu(WO4)2/BaWO4 Raman laser

A compact simultaneous actively Q-switched and mode-locked eye-safe Raman laser employing Nd:KLu(WO4)2 as gain medium and BaWO4 as Raman medium with high mode-locking repetition-rate is demonstrated. The picosecond first Stokes at 1549nm based on the fundamental laser emission at 1355nm is realized....

Zusammenfassung:A compact simultaneous actively Q-switched and mode-locked eye-safe Raman laser employing Nd:KLu(WO4)2 as gain medium and BaWO4 as Raman medium with high mode-locking repetition-rate is demonstrated. The picosecond first Stokes at 1549nm based on the fundamental laser emission at 1355nm is realized. With an absorbed pump power of 14.6W and pulse repetition frequency of 20kHz, a maximum output power of 1.4W with the mode-locking pulse repetition rate of 1.6GHz is obtained; the corresponding mode-locking pulse width is approximate 28ps.
