Compact dual-wavelength Nd:GdVO_4 laser working at 1063 and 1065 nm

Abstract

We report a compact diode-laser pumped Nd:GdVO(4) laser with stable dual-wavelength output at 1063 nm and 1065 nm simultaneously. Two types of resonant cavity configurations were presented to support the stable dual-wavelength operation of the laser. Using a polarization beam splitter(PBS) included T-shaped cavity, we obtained a total power output over 5 W in two orthogonal polarized beam directions with 4 W in sigma polarization (1065.5 nm) and 1 W in pi polarization (1063.1 nm). By combining a half-wave-plate with the PBS in the laser cavity, a new configuration favoring one beam direction dual-wavelength output with same polarization direction was realized. A phenomenon of further line splitting was observed in both 1065 nm and 1063 nm.

Recent Progress on Compact and Portable Terahertz Source Based on Parametric Conversion from Dual-Frequency Solid-State Laser Pulses

Recent progress on terahertz generation based on difference frequency generation: from power scaling to compact and portable sources (Invited Paper)

“…Although a Q-switched Nd:YLF laser has been implemented at 1 053 nm [36] , the simultaneous lasing of the two wavelengths has not been achieved. Aside from the Nd:YLF crystal, other combinations of the active ions and host materials can also emit two different frequencies [37] . The Q-switched solid-state lasers may be one of the optimal choices for implementing a compact THz source based on DFG.…”

Dual-wavelength CW a-cut Nd:YVO4 laser at 1064.3 and 1066.7 nm

“…Nd 3+ -doped gain materials, such as Nd:GYSGG, Nd:GdVO4, Nd:YAG, Nd:YLF and Nd:YVO4, are widely used in such lasers due to their high gain, broad absorption band, and good mechanical properties [5][6][7][8].…”
