Can fibers replace OPOs?

2013 IEEE Photonics Conference, 2013
We present a class of fibers that exploit light propagation in higher-order modes, and hence decouple the dispersion-versus-mode-area trade-off encountered in conventional fibers. This enables exploiting the multitude of nonlinear optical effects afforded by fibers, at energy levels potentially approaching those of tunable solid-state lasers.

Mid-IR ZGP-OPO pumped by a Bragg grating line-narrowed PPKTP-OPO

2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 2006
Here we report on a tandem OPO consisting of a Type I PPKTP-OPO pumping a ZGP-OPO generating radiation in the mid-IR. The PPKTP-OPO uses a bulk Bragg grating to generate narrowband pump radiation at 2008 nm.

Hybrid intra-extra cavity OPO using monolithic crystal for improvement in OPO efficiency

SPIE Proceedings, 2007
An intra-extra (hybrid) cavity Optical Parametric Oscillator (OPO) using monolithic KTP crystal has been built for converting 1064nm Nd:YAG laser radiation into 1572nm eye safe wavelength with high total conversion efficiency. Here a monolithic X-cut KTP crystal, having HR coating for 1064nm on the output face, was used external to the Nd:YAG laser.

Ultrashort pulse OPO ring laser

Conference on Lasers and Electro-Optics (CLEO 2000). Technical Digest. Postconference Edition. TOPS Vol.39 (IEEE Cat. No.00CH37088), 2000
Summary form only given. A ring cavity optical parametric oscillator (OPO) can be pumped synchronously in one direction by a Ti:sapphire fs laser. It can be operated in the other direction by sending the pump pulses from the opposite direction. The crossing point between the two pulse trains of the OPO can be adjusted by introducing a delay line in one

Compact, Q-switched, intracavity OPO

Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics. Postconference Edition. CLEO '99. Conference on Lasers and Electro-Optics (IEEE Cat. No.99CH37013), 2003
Summary form only given. In recent years there has been much interest in miniature optical parametric oscillators (OPOs) as sources of tuneable coherent radiation. We report an intracavity OPO based on an actively Q-switched semi-monolithic Nd:YVO/sub 4/ microchip laser and PPLN. The novelty of this OPO lies in its simple compact (

Nd:YVO4 pumped degenerate PPLN OPO

Advanced Solid-State Photonics, 2006
Conversion efficiencies of 44% and 56% are demonstrated in single and double-pass pump geometries respectively for a degenerate 1 micron pumped PPLN OPO. Pump feedback in the double-pass geometry acts as a pulse shortening mechanism.
