With the arrival of latest nonlinear materials and single-frequency pump sources, There may be renewed desire in optical parametric oscillators (OPOs). Just one-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely each amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
1 observes a dramatic increase in generation of the 2nd harmonic together with the demodulation alerts vs . the pump wave amplitude. A clear correlation exists involving these nonlinear signatures and the amount of damages. Preliminary determinations of your coefficient of quadratic nonlinearity are already attained. The final results from the configuration of parametric emitting antenna are believed to generally be the pretty to start with on cracked materials.
The initial-principles density useful calculations are performed to review the geometries and electronic constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite structures, and also the optical properties of all crystals are investigated systematically. The results suggest that these compounds have comparable band structures as well as band gap decreases from S to Se to Te. For the linear optical Attributes, 3 crystals display very good gentle transmission inside the IR and aspect obvious locations, and particularly, HgGa2S4 and HgGa2Se4 crystals have reasonable birefringence.
A straightforward method for lowering the decline that is because of depolarization ensuing from thermally induced anxiety birefringence in solid-point out lasers is documented. The system takes advantage of just one intracavity quarter-wave plate with its fast or sluggish axis aligned parallel to the popular plane of polarization, described by an intracavity polarizer.
We report new experimental effects around the phase-matching Attributes of yellow shade HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers while in the 0.944-ten.5910 μm range. Also, we present new Sellmeier equations that supply a superior reproduction in the current experimental success together with the published knowledge points for 2nd-harmonic era of CO2 laser radiation at nine.
PA Ref-mobile, which substantially lowers themeasurement faults in the methane concentration in thecase of instability
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are analyzed applying perturbation principle beneath the situation of rotating wave approximation. The 2 parametric FWM processes are coupled when they're fired up coherently by a brief laser pulse by using a bandwidth encompassing the two check here corresponding higher Strength ranges in The 2 FWM procedures.
Pumping mid-IR optical parametric oscillators close to one μm is desirable for its simplicity and ability scaling ability. To this aim, huge bandgap non-oxide nonlinear crystals are necessary.
Reliable state polymerization of diacetylenes The crystal composition of HAlSi2O6 with a keatite-kind framework Syntheses and crystal buildings of α
The technological innovation of growing mercury thiogallate crystals (HgGa2S4) is improved and high-excellent bulk samples are generated. The essential optical and thermal Houses of these crystals are researched. The transmission spectra of mercury thiogallate are calculated and its nonlinear properties like the quadratic susceptibility, tuning curves, plus the optical-harm resistance are decided.
Interference is observed involving the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
Note: Author names is going to be searched during the keywords area, also, but which could uncover papers wherever the individual is mentioned, instead of papers they authored.
On this paper we theoretically look into essentially the most productive pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Examination consists of solving the optimal Regulate issue utilizing the price equation formalism. The OPO exceptional buildup behavior is derived for virtually any OPO configuration, and we present that the exceptional pump pulse condition is actually a double rectangle. The primary rectangle is optimized for that buildup procedure, whilst the 2nd 1 is optimized for that constant state, and equally depend in different ways over the OPO mirror reflectivities and also the accessible pump Electricity and maximum peak electrical power.
three% rms around 12 h in great beam good quality. The in close proximity to-IR sign pulses from your OPO Have a very Gaussian pulse duration of �?19 ps , measured at 1284 nm. Now we have investigated the temperature tuning properties on the OPO and as opposed the info While using the theoretical calculations applying The newest Sellmeier equations and thermo-optic coefficients for your crystal. To the ideal of our understanding, Here is the first picosecond OPO based upon CSP running at MHz repetition charges.
