We review the progress in the development of continuous-wave optical parametric
oscillators over the last decade. A recently developed theoretical analysis shows that their …

Various infrared up-conversion techniques have been developed, driven by applications
including lasing, laser cooling, and infrared imaging. In this review article, we first present a …

We review the physical properties, linear and nonlinear optical characteristics, and phase‐
matching configurations of BiB3O6 (BIBO), the first low‐symmetry (monoclinic) inorganic …

We report on frequency-doubling characteristics of high-power, ultrafast optical vortex
beams in a nonlinear medium. Based on single-pass second-harmonic generation (SHG) of …

We present a stable, high-power, fiber-laser-pumped, continuous-wave (cw), singly resonant
optical parametric oscillator (SRO) for the mid-infrared in an output-coupled (OC) …

The quasi-phase-matching (QPM) technique has drawn increasing attention due to its
promising applications in areas such as nonlinear frequency conversion for generating new …

We describe the development of versatile, practical, and high-power ultrafast optical sources
based on second-order nonlinear frequency conversion in bulk materials pumped by the …

Since the publication of an earlier review on optical parametric oscillators (OPOs) in 2000, 1
there has been remarkable progress in the technological development and applications of …

We describe a wide range of versatile, practical and high-power sources of coherent
continuous-wave (cw) radiation from the near-to mid-infrared (mid-IR) to the visible and …

We present an efficient and tunable source generating multi-watt single-frequency red
radiation by intra-cavity frequency doubling of the signal in a MgO-doped periodically poled …
