Passively Q-switched diode-pumped Tm, Ho:LuVO₄ laser with a black phosphorus saturable absorber*

Abstract

Abstract We presented a passively Q -switched (PQS) diode-pumped c -cut Tm, Ho:LuVO 4 laser with a black phosphorus saturable absorber for the first time. Under PQS mode, an average output power of 0.86 W and a peak power of 2.32 W were acquired from the Tm, Ho:LuVO 4 laser with the pump power of 14.55 W, corresponding to a pulse width of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mn>2.89</mml:mn> <mml:mspace width="0.50em"/> <mml:mi mathvariant="normal">μ</mml:mi> <mml:mi mathvariant="normal">s</mml:mi> </mml:math> , a pulse repetition rate of 71.84 kHz, and a pulse energy of about <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" overflow="scroll"> <mml:mn>6.70</mml:mn> <mml:mspace width="0.50em"/> <mml:mi mathvariant="normal">μ</mml:mi> <mml:mi mathvariant="normal">J</mml:mi> </mml:math> .
