“…Smith et al [23] developed a classical model of a pulsed INOPO operating inside a ring cavity and compared this to experimental results, finding reasonable agreement with their predictions for spatial beam quality, spectral performance and beam profiles. The ability to efficiently generate tunable frequencies in the mid infrared via injection seeding was demonstrated by Haidar and Ito [24], who also showed a noticeable narrowing of the signal linewidth due to the injection.…”

In this paper we study the nondegenerate optical parametric oscillator with injected signal, both analytically and numerically. We develop a perturbation approach which allows us to find approximate analytical solutions, starting from the full equations of motion in the positive Prepresentation. We demonstrate the regimes of validity of our approximations via comparison with the full stochastic results. We find that, with reasonably low levels of injected signal, the system allows for demonstrations of quantum entanglement and the Einstein-Podolsky-Rosen paradox. In contrast to the normal optical parametric oscillator operating below threshold, these features are demonstrated with relatively intense fields.

“…Tunable lasers based on optical parametric oscillation with nonlinear crystals are of greatest interest. Nd pulse lasers are conventionally used as a source of parametric oscillator pumping, while nonlinear crystals (NLC) KNbO 3 , LiNbO 3 , KTP, KTA, etc. [1] serve for frequency conversion.…”

“…At present the feature analysis of extra-cavity OPO with LiNbO 3 resulted in a quantity of optical schemes [2][3][4][5][6][7]. The study of basic linear networks of OPO cavities [3,4] has shown that at satisfactory energy indictors the oscillator's divergence angle is rather high and runs up at the pumping energy increase.…”

A continuously or/and discontinuously tunable LiNbO 3 Optical Parametric Oscillator (OPO) with the spectral range of 1.42 -4.24 um and shifting of 0…12 nm is created and investigated. The OPO resonator ring circuit provides for the radiation energy output value of up to 50 mJ. Radiation bandwidth narrowing of up to 0.7 cm -1 by introducing of the Fabry-Perot etalon into the OPO resonator has been obtained.

“…Inspired by recent developments in high performance injection-seeded nanosecond OPOs 1,2,16,[22][23][24][25][26][27][28][29][30] combined with remarkable improvements in the tunability and long-term stability of diode lasers, our approach uses a mid-IR OPO, where FT-limited pulses can be readily obtained by injection seeding with a low power SLM diode laser. Subsequently, frequency upconversion is accomplished by mixing the mid-IR OPO output with the fourth harmonic of an injectionseeded Nd:yttrium aluminum garnet ͑YAG͒ laser, which is concurrently used to pump the OPO with the residual second harmonic.…”

Generation of programmable near-Fourier-transform-limited pulses of narrow-band laser radiation from the near infrared to the vacuum ultraviolet Rev. Sci. Instrum. 76, 103103 (2005) Nanosecond optical pulses with high power and spectral brightness in the deep ultraviolet ͑UV͒ region have been produced by sum frequency mixing of nearly transform-limited-bandwidth IR light originating from a home-built injection-seeded ring cavity KTiOPO 4 optical parametric oscillator ͑OPO͒ and the fourth harmonic beam of an injection-seeded Nd:YAG laser used simultaneously to pump the OPO with the second harmonic. We demonstrate UV output, tunable from 204 to 207 nm, which exhibits pulse energies up to 5 mJ with a bandwidth better than 0.01 cm −1 . We describe how the approach shown in this paper can be extended to wavelengths shorter than 185 nm. The injection-seeded OPO provides high conversion efficiency ͑Ͼ40% overall energy conversion͒ and superior beam quality required for highly efficient downstream mixing where sum frequencies are generated in the UV. The frequency stability of the system is excellent, making it highly suitable for optical pumping. We demonstrate high resolution spectroscopy as well as optical pumping using laser-induced fluorescence and stimulated emission pumping, respectively, in supersonic pulsed molecular beams of nitric oxide.
