With the appearance of new nonlinear resources and solitary-frequency pump sources, There exists renewed fascination in optical parametric oscillators (OPOs). Only one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's both amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Output idler energies over the microjoule stage are obtained with greatest conversion performance of eleven% for the amplifier stage, that is more than two occasions a lot better than the outcomes received by having an analogous sample of the broadly spread product AgGaS two .

A straightforward system for decreasing the decline that is because of depolarization ensuing from thermally induced stress birefringence in sound-state lasers is noted. The method works by using an individual intracavity quarter-wave plate with its speedy or sluggish axis aligned parallel to the preferred aircraft of polarization, outlined by an intracavity polarizer.
In addition, the coherent beam combination and divided pulse amplification technique to additional boost pulse energy are summarized. At the conclusion of this critique, we current a detailed overview of your purposes of femtosecond pulses including the generation of supercontinuum and tunable femtosecond pulses, plus some useful applications. Quite a few Views and analysis Instructions of femtosecond pulses may also be dealt with.
This double rectangle is quantitatively described and is also consistent with past effects noted from the literature. Also, numerical simulations are accustomed to validate our analytical product on the doubly resonant OPO and exhibit constant final results. The numerical simulations also demonstrate that an optimum prime-hat temporal profile could give performances pretty near to the ones attained With all the optimal double rectangle.
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are researched working with perturbation idea beneath the situation of rotating wave approximation. The two parametric FWM procedures are coupled when they are enthusiastic coherently by a short laser pulse which has a bandwidth encompassing the two corresponding higher Electrical power levels in the two FWM processes.
We present a numerical analyze for the design of productive MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top-hat transverse depth profile, and a double-go pump cavity configuration. Specifically, we investigate the impact of area condition to the conversion performance. We deemed two types of domain buildings: "best vertical-wall" and "wedge-formed" domains and our numerical success clearly show that at bigger pump pulse energies, the conversion performance saturates, as well as the saturated efficiency is nearly unbiased of the domain styles.
What's more, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled that the spectral profile from the output from the CPOPO was pertinent to the two the parametric gain profile of the nonlinear crystal as well as intra-cavity superior-buy dispersion.

The defect chalcopyrite crystal HgGa2S4 has actually been employed inside a 1064-nm pumped optical parametric oscillator to make Nonlinear crystals for optical parametric oscillators pumped by light pulses of close to IR lasers...
Quantum mechanical centered very first basic principle calculations are actually employed to acquire the unit mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite structure for the first time. For this, we treated HgGa2S4 in two differing types read more of web page symmetries in the exact same space group.
In this paper we theoretically look into by far the most productive pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Examination consists of fixing the optimum Command dilemma using the amount equation formalism. The OPO optimum buildup actions is derived for just about any OPO configuration, and we show the optimal pump pulse form is a double rectangle. The initial rectangle is optimized for your buildup system, although the 2nd a single is optimized with the regular point out, and both rely in another way within the OPO mirror reflectivities in addition to the available pump Vitality and most peak electrical power.
This is the initial example of a broadband OPO working over the molecular fingerprint area, and we reveal its potential by conducting broadband Fourier-remodel spectroscopy employing drinking water vapor and also a polystyrene reference standard.
