and running situations for the sensible style and design of large electric power femtosecond optical parametric oscillators with excitation
We report on the femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) determined by the Kerr-lens-method-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based upon the nonlinear crystal, CdSiP 2 , synchronously pumped inner to some MgO:PPLN femtosecond OPO, We have now created broadly tunable radiation across 5958�?117 nm employing rapid static cavity delay tuning, which has a highest electrical power of sixty four μW at 6791 nm, restricted via the absorption in mirror substrates as well as polarization-dependent intracavity losses.

By utilizing intracavity dispersion Regulate, around-remodel-confined signal pulses of �?100 fs length with clean single-peak spectrum are attained at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the ideal of our information, This is often the first time these types of sensible idler powers during the deep-IR happen to be generated from the dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition rate.
We report new experimental benefits within the section-matching Houses of yellow color HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-10.5910 μm range. Also, we present new Sellmeier equations that offer a fantastic replica on the present experimental success and also the printed data factors for next-harmonic generation of CO2 laser radiation at nine.
prompted oscillations in the idler wavelength of lower than 200MHz in excess of 300s; the limited-phrase stability was lower than 3MHz
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are researched applying perturbation principle beneath the condition of rotating wave approximation. The two parametric FWM processes are coupled when they're energized coherently by a brief laser pulse with a bandwidth encompassing the two corresponding higher Strength stages in the two FWM procedures.
Based on the theories of section matching and acceptable composition ratio, the impact of composition ratio to the frequency conversions of two forms (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration of corresponding sellmeier equations, period matching diagrams of 2nd harmonic technology and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers have been calculated, as well as appropriate composition ratios with different compositions.
In addition, we carried out a numerical simulation of chirped-pulse OPOs (CPOPOs) and unveiled that the spectral profile from the output from a CPOPO was relevant to both of those the parametric attain profile of your nonlinear crystal and also the intra-cavity significant-buy dispersion.
This paper opinions the modern developments in crystal progress and singly resonant optical parametric oscillators for your generation of superior one pulse Strength and common powers within the mid-IR from three to 10 μm.
... The very first information about the refractive index of orange HGS revealed by Levine et al. [35] provided only couple of wavelengths within the visible and in close proximity to-IR just as a demonstration in the feasibility of this crystal for birefringent phase-matching. The refractive indices with the orange phase were being calculated and tabulated among 0.
Quantum mechanical dependent initially theory calculations have been utilized to acquire the device mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for the first time. For this, we handled HgGa2S4 in two differing types of web site symmetries in the identical House team.
An easy quantum design agrees well Using the experimental benefits and makes it achievable to interpret the result regarding
This is actually the to start with HgGa2S4 Crystal example of a broadband OPO functioning through the molecular fingerprint location, and we show its potential by conducting broadband Fourier-rework spectroscopy employing h2o vapor and also a polystyrene reference common.
