Passive Q-switch mode-locking of 1.34 μ m Nd:GdVO4 lasers with Co2+:LMA saturable absorber

A diode‐end‐pumped passively Q‐switched modelocked Nd:GdVO4 laser operating at 1.34 μ m by using the Co2+:LaMgAl11O19 (Co2+:LMA) as the saturable absorber in a Z‐type cavity has been demonstrated in our experiment for the first time. The repetition rate of the Q‐switched pulse envelop increases from...

Zusammenfassung:	A diode‐end‐pumped passively Q‐switched modelocked Nd:GdVO4 laser operating at 1.34 μ m by using the Co2+:LaMgAl11O19 (Co2+:LMA) as the saturable absorber in a Z‐type cavity has been demonstrated in our experiment for the first time. The repetition rate of the Q‐switched pulse envelop increases from 4.2 kHz to 17 kHz as the pump power increases from 3.8 W to 8.9 W, and a maximum Q‐switched and modelocked fundamental mode average output power of 126 mW is obtained. The mode‐locked pulse inside the Q‐switched pulse has a repetition rate of 114 MHz, and its average pulse width is estimated to be about 280 ps.
