Intracavity singly-resonant optical parametric oscillator pumped by a semiconductor disk laser

Abstract

A novel scheme of the compact intracavity singly-resonant optical parametric oscillator (OPO) pumped by a semiconductor disk laser is presented. The cavity of the device is shared between the laser's optical field (the pump of the OPO) and the signal radiation emitted by the OPO. The length of the cavity doesn't exceed 10 mm that should hopefully favor for a single mode operational regime without any frequency selective elements (e.g. Fabry-Perot etalons). By estimation, the idler wavelength could be tuned over a few percents in the mid-infrared range (~ 17 μm) as the primary pump power is changed.
