.. [Exhibit entire abstract] parametric oscillator. The 2 independently concentrated beams have been manufactured to overlap In the crystal. The focusing parameters of the two beams were regarding the same. The concentrating function produced by Boyd and Kleinman for tightly concentrated beams was extended to periodically poled crystals to be able to healthy the temperature-tuning curve. A 0.66%/W efficiency was acquired for the real difference frequency mixing procedure.
We report on the femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) according to the Kerr-lens-method-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP two , synchronously pumped internal into a MgO:PPLN femtosecond OPO, Now we have generated broadly tunable radiation throughout 5958�?117 nm employing swift static cavity hold off tuning, having a optimum electricity of sixty four μW at 6791 nm, minimal because of the absorption in mirror substrates together with polarization-dependent intracavity losses.

An easy strategy for minimizing the loss that is due to depolarization ensuing from thermally induced pressure birefringence in good-state lasers is described. The procedure makes use of one intracavity quarter-wave plate with its rapid or slow axis aligned parallel to the popular plane of polarization, described by an intracavity polarizer.
We report new experimental success over the stage-matching Attributes of yellow color HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm variety. In addition, we present new Sellmeier equations that supply a excellent replica in the current experimental results and also the revealed facts details for second-harmonic technology of CO2 laser radiation at nine.
With this Introduction we will provide a shorter overview of your essential milestones in the development of solid-state lasers, discuss the selection of efficiency parameters doable Using these lasers, and point out significant applications.
The technology of tunable pico- and femtosecond light pulses with parametric frequency conversion procedures has captivated improved focus recently1. New crystal supplies, as BBO, LBO, and KTP, with exceptional nonlinearity and high harm threshold at the moment are out there, and pump lasers of improved balance enable the dependable Procedure of optical parametric oscillators. Parametric products pumped ... [Show complete abstract] either by cw modelocked lasers or by solitary extreme ultrashort pulses are already made. During this contribution parametric programs are talked about that are pumped by rigorous pulse trains of a few microseconds length and repetition charges approximately 50Hz.
A way is developed to resolve the system of shortened equations describing parametric era in website a just one-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals and the ideal reflection coefficient of your output mirror are approximated vs . the pump Power density Wp at unique values from the OPO nonstationarity .
Vibrational spectra of Li-made up of nonlinear crystals as well as their software in THz radiation technology are discussed. Employing an example of LiGaS2, the defect impact on spectroscopic characteristics is revealed. Large-temperature annealing in a proper atmosphere lets a single to get rid of prolonged and stage defects and to Increase the transparency. Energy composition and parameters of principal level defects including anion vacancy (File-center) and cation antisite defect GaLi calculated from the main concepts agree well With all the experimental results.
The know-how of escalating mercury thiogallate crystals (HgGa2S4) is enhanced and higher-high quality bulk samples are developed. The essential optical and thermal Homes of such crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear attributes including the quadratic susceptibility, tuning curves, as well as optical-destruction resistance also are determined.
Interference is observed amongst the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
The noticed f -to- two file frequency beats, originating straight from the OPO, can be utilized for self-referencing and phase locking with the pump laser comb without having for supercontinuum generation. With a median output energy of �?thirty mW , this set up might be effective for a range of spectroscopic apps in the mid-IR.
The chosen nonlinear crystals show higher nonlinear conversion efficiency compared to AgGaS two , with BaGa two GeS 6 Also offering a narrower angular spectrum of spontaneous parametric down conversion, advantageous in interferometric schemes. Our results build a pathway for integrating Superior crystal systems into mid-infrared metrology and imaging units, environment the stage for upcoming developments in nonlinear interferometry and spectroscopy.
three% rms over 12 h in fantastic beam high quality. The in close proximity to-IR signal pulses from your OPO Use a Gaussian pulse duration of �?19 ps , measured at 1284 nm. We have now investigated the temperature tuning characteristics in the OPO and when compared the data With all the theoretical calculations working with the most recent Sellmeier equations and thermo-optic coefficients for your crystal. To the top of our awareness, this is the very first picosecond OPO based upon CSP functioning at MHz repetition rates.
