With the appearance of latest nonlinear supplies and solitary-frequency pump sources, there is renewed curiosity in optical parametric oscillators (OPOs). Only one-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that's both amplified and frequency doubled is used to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Effects of thermal conductivity measurements are described for a number of of the greater a short while ago formulated nonlinear optical crystals. New or considerably revised values of thermal conductivity were attained in six materials. Noteworthy thermal conductivities calculated ended up All those for AgGaS2 [0.014 W/(cm K) and 0.
The main-principles density useful calculations are performed to review the geometries and electronic constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite structures, along with the optical Qualities of all crystals are investigated systematically. The effects indicate that these compounds have similar band buildings as well as band hole decreases from S to Se to Te. For your linear optical Qualities, three crystals clearly show excellent light-weight transmission while in the IR and portion seen regions, and especially, HgGa2S4 and HgGa2Se4 crystals have moderate birefringence.
An easy approach for decreasing the loss that is because of depolarization resulting from thermally induced stress birefringence in stable-condition lasers is reported. The system employs just one intracavity quarter-wave plate with its quick or gradual axis aligned parallel to the preferred airplane of polarization, defined by an intracavity polarizer.
Self-referenced octave-huge subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
caused oscillations inside the idler wavelength of fewer than 200MHz around 300s; the limited-time period security was lower than 3MHz
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are studied using perturbation idea beneath the problem of rotating wave approximation. The 2 parametric FWM processes are coupled when they're thrilled coherently by a brief laser pulse using a bandwidth encompassing The 2 corresponding higher Vitality levels in the two FWM procedures.
A way is created to unravel the technique of shortened equations describing parametric generation inside of a just one-frequency OPO cavity below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well as the ideal reflection coefficient from the output mirror are believed as opposed to the pump Power density Wp at various values in the OPO nonstationarity .
Furthermore, we performed a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed which the spectral profile of your output from the CPOPO was appropriate to both equally the parametric acquire profile of the nonlinear crystal along with the intra-cavity significant-buy dispersion.

Simple system for minimizing the depolarization loss resulting from thermally induced birefringence in solid-condition lasers
for that detection of molecular trace gasses. The oscillation threshold, output electrical power and steadiness of the single resonant
Mid-IR 2nd-order NLO crystal is indispensable from the frequency conversion programs in the mid-IR area. As opposed with DUV and UV/Vis/around-IR NLO crystals, simple mid-IR NLO crystals are comparatively scarce, and many of them are still for the stage of laboratory study. more info This chapter opinions the recent progress on the mid-IR NLO crystals, which largely features expanding the classical mid-IR NLO crystals into massive superior-top quality types or into quasi-stage-matching structures which can be appropriate for the laser units by a variety of progress methods and Checking out new probable mid-IR NLO crystals by introducing new style and design and synthesis tactics.
3% rms in excess of twelve h in excellent beam top quality. The around-IR signal pulses from the OPO Have a very Gaussian pulse length of �?19 ps , measured at 1284 nm. We've got investigated the temperature tuning attributes with the OPO and in comparison the data Together with the theoretical calculations applying The latest Sellmeier equations and thermo-optic coefficients with the crystal. To the best of our expertise, this is the initial picosecond OPO dependant on CSP functioning at MHz repetition fees.
