Abstract

Abstract

The output characteristics of a multi-wavelength tunable optical parametric oscillator (OPO) pumped by an all-solid-state Nd:YVO4 laser with the 1064 nm wavelength is investigated by quasi-phase-matching period tuning and temperature tuning technology. An experiment is carried out by using an external cavity structure and continuous wave (CW) operation mode, and changing the periods and temperature of a periodically poled MgO:LiNO3 crystal (PPMgLN) from 30 to 100 ℃ with 30.2 m, 30.4 m and 30.6 m grating period. The experimental results indicate that the threshold of the CW PPMgLN OPO is only 0.22 W and the different poling period needs different temperature-tuned range, and the continuously tunable near-infrared spectrum from 1 559.8 to 1 597.2 nm and mid-infrared spectrum from 3 187.3 to 3 347.3 nm are obtained. A continuously tunable PPMgLN-OPO at the signal and idler wavelength is realized.
