Multi-wavelength passively Q-switched red lasers with Nd3+:YAG/YAG/V3+:YAG/YAG composite crystal

We experimentally demonstrated a passively Q-switched red laser with an Nd 3+ :YAG/YAG/V 3+ :YAG/YAG composite crystal. Multi-wavelength operation at 659.5, 664 and 669 nm was observed. This is the first observation of the 1327.6 nm laser and its second harmonic generation from the Nd 3+ :YAG based...

More Information
Summary:We experimentally demonstrated a passively Q-switched red laser with an Nd 3+ :YAG/YAG/V 3+ :YAG/YAG composite crystal. Multi-wavelength operation at 659.5, 664 and 669 nm was observed. This is the first observation of the 1327.6 nm laser and its second harmonic generation from the Nd 3+ :YAG based system. The maximum average output power of red laser was 542 mW at the pumped power of 17.18 W. To the best of our knowledge, it is the highest output power of frequency-doubling red laser obtained in a passively Q-switched Nd 3+ :YAG system.
