053 μm. The absorption spectrum of ammonia was offered to display the feasibility on the developed optical parametric oscillator system for spectroscopic measurements and gasoline detection.
We report with a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) determined by the Kerr-lens-manner-locked Ti:sapphire laser as being the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP two , synchronously pumped internal to the MgO:PPLN femtosecond OPO, We've got produced broadly tunable radiation throughout 5958�?117 nm applying immediate static cavity hold off tuning, using a utmost ability of sixty four μW at 6791 nm, minimal through the absorption in mirror substrates as well as polarization-dependent intracavity losses.
A list of ~450 noncentrosymmetric sulfides has been observed in reference to nonlinear optical properties. It has been found that to the aircraft on the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
Scientific tests of viable pump laser systems appropriate for ultrafast femtosecond OPOs based on CdSiP two are reviewed, as well as favorable linear and nonlinear optical Qualities, as well as distinctive phase-matching qualities of CdSiP two , are offered using The newest Sellmeier equations for the material. The explained experimental benefits symbolize the highest output pulse energy and document average electricity inside the ultrafast picosecond and femtosecond time scales throughout the six–seven μm spectral variety so far.
We report new experimental results within the section-matching Homes of yellow color HgGa2S4 crystals for harmonic generation of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-10.5910 μm vary. Also, we existing new Sellmeier equations that offer a very good replica in the existing experimental effects in addition to the released information factors for second-harmonic generation of CO2 laser radiation at 9.
The large conversion effectiveness and wide range of radiation wavelength tuning enables to assume this content might compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the appreciable trouble of huge measurement crystals expansion system.
Optical properties of orange phased HgGa2S4 crystal is investigated. Era of tunable middle infrared radiation by 2nd harmonic of tunable CO2 laser radiation continues to be shown. Next harmonic conversion performance with regard to other infrared crystal has also been talked about.
According to the theories of stage matching and acceptable composition ratio, the influence of composition ratio to the frequency conversions of two forms (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, stage matching diagrams of second harmonic era and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers were calculated, and appropriate composition ratios with a variety of compositions.

Investigation of new, promising large-band-hole nonlinear crystals for that mid-IR is specified. We focused on ternary and quaternary chalcogenides and dependent on their own physical and chemical Attributes, which Besides linear and nonlinear optical Homes, decide the performance of crystal usage in selected laser experiments. The correlation in between the composition, construction and output parameters as well as the trends in adjustments of the key characteristics for example band gap, nonlinear susceptibility, laser harm threshold, and so on, are demonstrated.
Interference is observed involving the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
Note: Creator names are going to be searched inside the keywords and phrases area, also, but that will obtain papers in which the person is stated, as opposed to papers they authored.
In this particular paper we theoretically look into quite possibly the most successful pump temporal form for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Investigation is made up of fixing the ideal Handle issue using the amount equation formalism. The read more OPO best buildup conduct is derived for almost any OPO configuration, and we present which the optimum pump pulse condition is often a double rectangle. The first rectangle is optimized for that buildup method, though the next 1 is optimized for the steady point out, and both of those count in a different way to the OPO mirror reflectivities plus the accessible pump energy and utmost peak electrical power.
three% rms about 12 h in good beam good quality. The near-IR sign pulses in the OPO have a Gaussian pulse length of �?19 ps , measured at 1284 nm. We now have investigated the temperature tuning qualities of the OPO and in contrast the info With all the theoretical calculations using The latest Sellmeier equations and thermo-optic coefficients for that crystal. To the very best of our information, this is the initially picosecond OPO based on CSP working at MHz repetition charges.
