.. [Demonstrate full summary] parametric oscillator. The two independently targeted beams had been manufactured to overlap Within the crystal. The concentrating parameters of The 2 beams have been about the similar. The concentrating function developed by Boyd and Kleinman for tightly centered beams was prolonged to periodically poled crystals in order to suit the temperature-tuning curve. A 0.sixty six%/W performance was acquired for the primary difference frequency mixing course of action.
We report with a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) determined by the Kerr-lens-manner-locked Ti:sapphire laser since the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP 2 , synchronously pumped inner to a MgO:PPLN femtosecond OPO, We have now produced broadly tunable radiation throughout 5958�?117 nm applying speedy static cavity hold off tuning, which has a utmost ability of sixty four μW at 6791 nm, constrained from the absorption in mirror substrates along with polarization-dependent intracavity losses.
crystals with ultrafast Yb-ion laser pump is proposed. The final results form a beneficial reference for the choice of resources
By implementing intracavity dispersion Regulate, in close proximity to-rework-minimal sign pulses of �?one hundred fs duration with sleek one-peak spectrum are obtained at 1264 nm, comparable to an idler wavelength at 6440 nm. To the top of our know-how, That is the first time these useful idler powers in the deep-IR are created from the dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition fee.
OPO were being improved by optimizing pump beam waist and OPO cavity length. The two air-spaced and good etalons had been tested to frequency
brought about oscillations within the idler wavelength of fewer than 200MHz over 300s; the quick-term steadiness was under 3MHz
Taxonomy, chemical bonding relations and nonlinear optical Qualities of noncentrosymmetric sulfide crystals
This new version has long been up to date and revised to includeimportant developments, ideas and systems that haveemerged Because the publication of the main edition.

The know-how of growing mercury thiogallate crystals (HgGa2S4) is enhanced and significant-high quality bulk samples are manufactured. The basic optical and thermal Qualities of these crystals are examined. The transmission spectra of mercury thiogallate are measured and its nonlinear characteristics such as the quadratic susceptibility, tuning curves, along with the optical-hurt resistance may also be identified.
The defect chalcopyrite crystal HgGa2S4 is used inside of a 1064-nm pumped optical parametric oscillator to deliver Nonlinear crystals for optical parametric oscillators pumped by light-weight pulses of in close proximity to IR lasers...
The observed f -to- two file frequency beats, originating directly from the OPO, can be utilized for self-referencing and stage locking of the pump laser comb without having for supercontinuum technology. With a median output energy of �?thirty mW , this set up may very well be useful for a range of spectroscopic apps while in the mid-IR.
Mid-IR next-order NLO crystal is indispensable inside the frequency conversion programs in the mid-IR region. Compared with DUV and UV/Vis/in the vicinity of-IR NLO crystals, useful mid-IR NLO crystals are reasonably unusual, and lots of of these remain with the phase of laboratory research. This chapter evaluations the new development around the mid-IR NLO crystals, which mainly incorporates growing the classical mid-IR NLO crystals into big higher-good quality ones or into quasi-phase-matching structures that are well suited for the laser gadgets by a variety of expansion methods and Discovering new probable mid-IR NLO crystals by introducing new structure and synthesis approaches.
three% rms about twelve h in very good beam good quality. The close to-IR signal pulses in the OPO Use a Gaussian pulse period of �?19 ps , measured at 1284 nm. We here have now investigated the temperature tuning attributes on the OPO and when compared the information With all the theoretical calculations making use of The newest Sellmeier equations and thermo-optic coefficients for the crystal. To the top of our knowledge, this is the first picosecond OPO based on CSP functioning at MHz repetition fees.
