The 2-Minute Rule for HgGa2S4 Crystal

Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency generation in OPGaAs

We report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser given that the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP two , synchronously pumped interior to your MgO:PPLN femtosecond OPO, We now have generated broadly tunable radiation throughout 5958�?117 nm working with speedy static cavity hold off tuning, using a utmost electricity of 64 μW at 6791 nm, confined through the absorption in mirror substrates and polarization-dependent intracavity losses.

By employing intracavity dispersion Manage, in the vicinity of-change-restricted signal pulses of �?a hundred fs period with easy solitary-peak spectrum are obtained at 1264 nm, comparable to an idler wavelength at 6440 nm. To the ideal of our understanding, this is The very first time these realistic idler powers during the deep-IR happen to be created from a dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition charge.

Self-referenced octave-wide subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser

This double rectangle is quantitatively described and is in keeping with previous results described while in the literature. Also, numerical simulations are utilized to validate our analytical model with a doubly resonant OPO and display regular results. The numerical simulations also present that an exceptional leading-hat temporal profile could deliver performances pretty near the ones realized Together with the ideal double rectangle.

Ultrafast femtosecond manner-locked fiber laser performs an indispensable position in health-related imaging, space ranging, ophthalmology, terahertz spectroscopy, product micromachining, etc. It’s not just an essential Software for persons to investigate the world, and also a pillar discipline of laser technologies. This evaluation existing the era of femtosecond pulses in ultrafast manner-locked fiber lasers making use of Energetic, passive, hybrid mode-locking tactics, the emphasis is given to passively method-locked fiber lasers. Concerning the optimization of femtosecond pulses, we introduce the external compression strategy to acquire shorter pulse width, chirped pulse amplification method to extend pulse energy and procure substantial Strength femtosecond pulses at the practical band.

air gap and fired up in series by a common pump beam. The section of your interference depends on the section shifts at 3 frequencies.

Better-order nonlinear procedures in alternative resources may also be considered and also a discussion on product suitability for down-conversion of around-IR lasers in to the mid-IR to fulfill numerous software demands can also be introduced.

The technological innovation of developing mercury thiogallate crystals (HgGa2S4) is improved and superior-excellent bulk samples are made. The basic optical and thermal Houses of those crystals are studied. The get more info transmission spectra of mercury thiogallate are calculated and its nonlinear qualities including the quadratic susceptibility, tuning curves, plus the optical-injury resistance are established.

The defect chalcopyrite crystal HgGa2S4 is employed in a 1064-nm pumped optical parametric oscillator to generate Nonlinear crystals for optical parametric oscillators pumped by light-weight pulses of in close proximity to IR lasers...

A pulsed TEA CO2 laser was applied to investigate the influence of pump radiation parameters (mode structure, wavelength, and pulse duration), focusing situations, absorption coefficient, and temperature over the performance of conversion into the next harmonic and on angular dependences of period matching in ZnGeP2 crystals. Superior settlement betweeen experimental and theoretical outcomes is observed. Browse extra

Diode-pumped optical parametric oscillation has actually been demonstrated for the first time to our knowledge in one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take in the 812-nm radiation to produce 1084-nm laser oscillation.
