Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAs
Output idler energies on the microjoule degree are attained with highest conversion performance of 11% for that amplifier stage, and that is much more than two instances much better than the results acquired using an analogous sample of your commonly distribute material AgGaS 2 .
A list of ~450 noncentrosymmetric sulfides has long been noticed in reference to nonlinear optical Houses. It's been located that about the airplane of the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
.. [Show entire summary] third-harmonic era and parametric amplification with very low-frequency pumping in periodically poled active nonlinear crystals are investigated. The Examination is completed for the situation of a periodically poled Nd:Mg:LiNbO3 crystal. Views of working with periodically poled Energetic nonlinear crystals in laser gadgets with self-frequency conversion are mentioned.
OPO have been improved by optimizing pump beam waistline and OPO cavity length. The two air-spaced and sound etalons had been examined to frequency
During this Introduction we will give a short overview of the crucial milestones in the development of sound-condition lasers, explore the choice of general performance parameters probable Using these lasers, and point out main apps.
Optical Qualities of orange phased HgGa2S4 crystal is investigated. Era of tunable Center infrared radiation by second harmonic of tunable CO2 laser radiation has become shown. Next harmonic conversion efficiency with respect to other infrared crystal has also been reviewed.
A technique is developed to solve the technique of shortened equations describing parametric technology inside of a one-frequency OPO cavity under nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals as well as the ideal reflection coefficient on the output mirror are estimated versus the pump Power density Wp at distinct values in the OPO nonstationarity .
The particular heat and thermal conductivity of HgGa2S4 are measured. It truly is concluded that the mixed Houses of HgGa2S4 crystals can offer for them a leading place One of the supplies used in nonlinear-optical gadgets for mid-IR-frequency conversion.
The 3rd harmonic of CO2-laser radiation is attained by passing the laser beam by two CdGeAs2 crystals in tandem, with the initial crystal oriented for next-harmonic generation and the next for sum mixing. Applying this technique, click here We now have accomplished a mean exterior conversion efficiency of 1.
... The initial information around the refractive index of orange HGS released by Levine et al. [35] involved only couple of wavelengths in the seen and close to-IR just as an indication in the feasibility of the crystal for birefringent phase-matching. The refractive indices for that orange period had been measured and tabulated involving 0.
The observed file -to- two file frequency beats, originating directly from the OPO, may be used for self-referencing and phase locking of your pump laser comb with no need for supercontinuum technology. With a median output power of �?thirty mW , this set up could possibly be useful for a number of spectroscopic applications during the mid-IR.
With this paper we theoretically investigate one of the most effective pump temporal form for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Evaluation consists of solving the best control challenge utilizing the price equation formalism. The OPO ideal buildup habits is derived for virtually any OPO configuration, and we display the exceptional pump pulse shape is really a double rectangle. The primary rectangle is optimized for that buildup system, while the second one is optimized for the regular state, and each depend differently on the OPO mirror reflectivities along with the available pump Power and optimum peak energy.
3% rms in excess of twelve h in superior beam quality. The in the vicinity of-IR signal pulses from your OPO Have a very Gaussian pulse length of �?19 ps , calculated at 1284 nm. We now have investigated the temperature tuning features of your OPO and compared the data Using the theoretical calculations making use of the most recent Sellmeier equations and thermo-optic coefficients for your crystal. To the most effective of our information, This is actually the initial picosecond OPO according to CSP operating at MHz repetition fees.
