With the appearance of new nonlinear elements and single-frequency pump resources, There's renewed fascination in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely both equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Output idler energies to the microjoule amount are obtained with most conversion efficiency of 11% for that amplifier stage, and that is a lot more than two times a lot better than the results acquired with an analogous sample from the commonly distribute materials AgGaS two .
A list of ~450 noncentrosymmetric sulfides has been observed in reference to nonlinear optical Homes. It has been uncovered that around the airplane in the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned into a rosette of two intersected ellipses of «acentricity».
By utilizing intracavity dispersion Command, in close proximity to-transform-restricted sign pulses of �?100 fs length with easy single-peak spectrum are attained at 1264 nm, akin to an idler wavelength at 6440 nm. To the ideal of our expertise, This really is The very first time such simple idler powers inside the deep-IR happen to be created from the dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition amount.
OPO ended up improved by optimizing pump beam midsection and OPO cavity length. The two air-spaced and strong etalons were being examined to frequency
This double rectangle is quantitatively explained and it is according to earlier outcomes noted inside the literature. Also, numerical simulations are used to validate our analytical model on a doubly resonant OPO and demonstrate consistent results. The numerical simulations also demonstrate that an exceptional prime-hat temporal profile could present performances extremely close to the ones attained With all the optimal double rectangle.
The technology of tunable pico- and femtosecond light pulses with parametric frequency conversion processes has attracted greater awareness recently1. New crystal materials, as BBO, LBO, and KTP, with outstanding nonlinearity and substantial problems threshold are now offered, and pump lasers of enhanced steadiness enable the reliable click here operation of optical parametric oscillators. Parametric products pumped ... [Show complete summary] possibly by cw modelocked lasers or by one intense ultrashort pulses are actually made. On this contribution parametric techniques are discussed that are pumped by intense pulse trains of a few microseconds length and repetition costs up to 50Hz.
We existing a numerical review for the look of effective MgO:PPLN dependent pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of leading-hat transverse depth profile, in addition to a double-go pump cavity configuration. Especially, we examine the impact of domain shape about the conversion effectiveness. We thought of two varieties of area constructions: "perfect vertical-wall" and "wedge-formed" domains and our numerical final results present that at bigger pump pulse energies, the conversion performance saturates, as well as saturated performance is almost impartial on the domain shapes.

Solitary-move sub-200 fs mid-infrared generation from an optical parametric oscillator synchronously pumped by an erbium fiber laser
This is actually the very first example of a broadband OPO running throughout the molecular fingerprint region, and we display its likely by conducting broadband Fourier-rework spectroscopy utilizing h2o vapor plus a polystyrene reference regular.
