053 μm. The absorption spectrum of ammonia was presented to show the feasibility on the produced optical parametric oscillator program for spectroscopic measurements and gas detection.
We report on the femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser because the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based on the nonlinear crystal, CdSiP two , synchronously pumped inner into a MgO:PPLN femtosecond OPO, We've produced broadly tunable radiation across 5958�?117 nm employing fast static cavity hold off tuning, that has a most ability of sixty four μW at 6791 nm, limited because of the absorption in mirror substrates together with polarization-dependent intracavity losses.
This method enables the operation of extensively tunable optical parametric oscillators2 (OPO) and subsequent change frequency generators3 making tunable pulses of higher peak electric power. The upper energy of your pump pulse trains has particular Positive aspects to the Procedure of the synchronously pumped OPO, e.g., peaceful steadiness prerequisites, along with the potential to operate with large cavity losses (e.g. metal mirrors) allowing for massive tuning ranges with only one set of mirrors and higher output-coupling factors for pulse shortening.
Scientific studies of viable pump laser technologies suitable for ultrafast femtosecond OPOs based upon CdSiP 2 are discussed, and the favorable linear and nonlinear optical Homes, and also special section-matching attributes of CdSiP 2 , are introduced utilizing the most recent Sellmeier equations for the fabric. The described experimental outcomes depict the highest output pulse Electrical power and document common electricity in the ultrafast picosecond and femtosecond time scales across the 6–7 μm spectral assortment so far.
OPO ended up improved by optimizing pump beam midsection and OPO cavity duration. Both equally air-spaced and stable etalons were examined to frequency
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Together with signal and idler, it may be consistently tuned from 1.261 via 2.532 μm by various the pump wavelength. Two main enhancements ended up accomplished, including the connection from the signal and idler tuning ranges along with the significant output pulse energy with the sign and idler tuning ... [Display complete abstract] ranges. The initial enhancement was attained by discovering two certain sets of period-matching angles. The next enhancement was realized by utilizing five sets of resonator mirrors for oscillating either signal or idler.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are studied making use of perturbation principle under the affliction of rotating wave approximation. The 2 parametric FWM processes are coupled when they're excited coherently by a brief laser pulse with a bandwidth encompassing The 2 corresponding upper Strength ranges in The 2 FWM procedures.

Additionally, we performed a numerical simulation of chirped-pulse OPOs (CPOPOs) and revealed which the spectral profile with the output from the CPOPO was suitable to equally the parametric achieve profile in the nonlinear crystal as well as the intra-cavity large-order dispersion.
The technologies of growing mercury thiogallate crystals (HgGa2S4) is enhanced and substantial-good quality bulk samples are developed. The basic optical and thermal Homes of those crystals are studied. The transmission spectra of mercury thiogallate are calculated and its nonlinear qualities including the quadratic susceptibility, tuning curves, and the optical-injury resistance are identified.
The system relies on group velocity matching in between interacting waves Along with birefringent phase matching. We are going to describe broadband SHG characteristics in terms of beam propagation directions, spectral positions of resonance, productive nonlinearities, spatial wander-offs amongst interacting beams, and spectral bandwidths. The outcomes will exhibit which the spectral bandwidths of the basic wave permitted for broadband SHG to reach numerous countless nm. read more The corresponding SH spectral range spans from 1758.58 to 4737.18 nm during the non-oxide crystals regarded Within this review. This sort of broadband SHG applying limited pulse trains can likely be placed on frequency up-conversion imaging inside the mid-IR location, in details transmission, As well as in nonlinear optical signal processing.
The observed file -to- 2 file frequency beats, originating directly from the OPO, can be used for self-referencing and section locking on the pump laser comb with no need for supercontinuum era. With an average output power of �?thirty mW , this setup is likely to be useful for a number of spectroscopic purposes while in the mid-IR.
A straightforward quantum model agrees well Using the experimental outcomes and causes it to be achievable to interpret the effect in terms of
