A new approach to outputting 2 m light was proposed based on non-critical phase matching KTA-OPO intra-cavity pumped by Nd:YVO4 crystal laser. A signal light with a power exceeding 1 W at 2093 nm is obtained with a diode-to-signal efficiency up to 10%. The short pulse width is about 3.4 ns at 30 kHz and the spectrum width at 2 m waveband is only about 1 nm. The results show that this approach is also an efficient way to achieve 2 m pulsed laser with high peak power.
