.. [Show whole abstract] parametric oscillator. The two independently centered beams ended up designed to overlap In the crystal. The focusing parameters of The 2 beams have been concerning the same. The focusing purpose produced by Boyd and Kleinman for tightly focused beams was prolonged to periodically poled crystals in order to suit the temperature-tuning curve. A 0.66%/W effectiveness was obtained for the real difference frequency mixing course of action.
A method-locked tunable dye laser has actually been created that's synchronously pumped at substantial repetition premiums because of the doubled output of the mode-locked Nd:YAG laser. The dye laser gives extreme pulses of 35 psec duration that happen to be greatly tunable, of near-remodel-limited bandwidth, As well as in time coincidence With all the pumping pulses.
The very first-ideas density functional calculations are done to check the geometries and Digital structures of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite buildings, as well as the optical Houses of all crystals are investigated systematically. The results point out that these compounds have equivalent band structures along with the band hole decreases from S to Se to Te. For the linear optical properties, a few crystals present excellent light transmission inside the IR and element obvious regions, and specifically, HgGa2S4 and HgGa2Se4 crystals possess average birefringence.
By employing intracavity dispersion Handle, around-change-constrained sign pulses of �?100 fs duration with smooth one-peak spectrum are attained at 1264 nm, similar to an idler wavelength at 6440 nm. To the best of our understanding, This is certainly The 1st time this kind of sensible idler powers during the deep-IR are actually created from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition amount.
We report new experimental final results on the phase-matching properties of yellow coloration HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm array. In addition, we current new Sellmeier equations that provide a very good copy on the present experimental effects plus the released facts details for 2nd-harmonic generation of CO2 laser radiation at nine.
This double rectangle is quantitatively explained and is in line with past outcomes claimed inside the literature. Also, numerical simulations are used to validate our analytical design with a doubly resonant OPO and exhibit reliable results. The numerical simulations also exhibit that an best leading-hat temporal profile could deliver performances incredibly close to those achieved Using the ideal double rectangle.
While utilizing an institutional account for this Web page we don’t keep track of any private, overall performance, practical or 1st or 3rd social gathering associated data.
According to the theories of stage matching and appropriate composition ratio, the influence of composition ratio around the frequency conversions of two types (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thing to consider of corresponding sellmeier equations, period matching diagrams of second harmonic era and optical parametric oscillations pumped by the popular click here Nd3+:YAG and Ho3+:YLF lasers ended up calculated, and appropriate composition ratios with a variety of compositions.

The defect chalcopyrite crystal HgGa2S4 has become used inside of a 1064-nm pumped optical parametric oscillator to produce Nonlinear crystals for optical parametric oscillators pumped by mild pulses of close to IR lasers...
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser method. By using a 300 μm long magnesium-doped periodically poled LiNbO 3 crystal as the parametric attain medium and configuring the OPO being a chirped-pulse oscillator, we obtained mid-infrared emission getting an instantaneous bandwidth masking 3084�?466 nm. This outcome signifies, to the most effective of our understanding, the widest instantaneous bandwidth attained from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the huge possible of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-fast OPOs.
A pulsed TEA CO2 laser was utilized to analyze the effect of pump radiation parameters (method framework, wavelength, and pulse period), focusing conditions, absorption coefficient, and temperature within the performance of conversion into the 2nd harmonic and on angular dependences of period matching in ZnGeP2 crystals. Great arrangement betweeen experimental and theoretical final results is noticed. Browse far more
This is actually the initial example of a broadband OPO running across the molecular fingerprint region, and we exhibit its likely by conducting broadband Fourier-change spectroscopy working with water vapor in addition to a polystyrene reference normal.
