Optical parametric oscillator pumped at ~one µm with intracavity mid-IR big difference-frequency technology in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) depending on the Kerr-lens-mode-locked Ti:sapphire laser as the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP 2 , synchronously pumped internal to a MgO:PPLN femtosecond OPO, Now we have created broadly tunable radiation across 5958�?117 nm utilizing rapid static cavity hold off tuning, by using a greatest ability of sixty four μW at 6791 nm, limited from the absorption in mirror substrates and polarization-dependent intracavity losses.

By implementing intracavity dispersion Command, in the vicinity of-completely transform-constrained signal pulses of �?a hundred fs length with sleek single-peak spectrum are accomplished at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the most effective of our information, This really is the first time this kind of simple idler powers while in the deep-IR have been produced from a dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition fee.
Within this get the job done, we current exactly what is, to our understanding, the 1st measurements of your quantum section diffusion sound of the cw OPO. Examine more
caused oscillations while in the idler wavelength of fewer than 200MHz more than 300s; the limited-expression security was a lot less than 3MHz
The temperature dependence of refractive indices of optical resources is characterized In this particular do the job by what we contact their normalized thermo-optic coefficients. They're decided experimentally by interferometric measurements of thermal growth and of modifications in optical thickness at several laser wavelengths as operate of temperature. A suitable vectorial formalism placed on these data allows predicting the thermal evolution of your refractive index all over the beneficial number of transparency.
A way is designed to solve the system of shortened equations describing parametric era inside of a just one-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well as best reflection coefficient on the output mirror are estimated versus the pump Strength density Wp at distinct values from the OPO nonstationarity .
Solid condition polymerization of diacetylenes The crystal composition of HAlSi2O6 which has a keatite-style framework Syntheses and crystal structures of α
The 3rd harmonic of CO2-laser radiation continues to be received by passing the laser beam through two CdGeAs2 crystals in tandem, with the 1st crystal oriented for next-harmonic era and the second for sum mixing. Utilizing this technique, Now we have accomplished a mean exterior conversion efficiency of 1.
The system is based on team velocity matching involving interacting waves Besides birefringent phase matching. We're going to describe broadband SHG features with regards to beam propagation Instructions, spectral positions of resonance, helpful nonlinearities, spatial walk-offs in between interacting beams, and spectral bandwidths. The outcomes will present that the spectral bandwidths of the fundamental wave allowed for broadband SHG to achieve various many hundreds of nm. The corresponding SH spectral range spans from 1758.fifty eight to 4737.eighteen nm within the non-oxide crystals regarded as With this analyze. This kind of broadband SHG making use of shorter pulse trains can perhaps be applied to check here frequency up-conversion imaging within the mid-IR location, in information and facts transmission, As well as in nonlinear optical signal processing.
fuel analyzers is performed. The created PA methane sensor is adapted for placement on the UAV’s board. Machine
Mid-IR next-get NLO crystal is indispensable from the frequency conversion applications from the mid-IR region. As opposed with DUV and UV/Vis/in the vicinity of-IR NLO crystals, useful mid-IR NLO crystals are rather exceptional, and a lot of of these remain on the phase of laboratory analysis. This chapter evaluations the new development around the mid-IR NLO crystals, which primarily includes growing the classical mid-IR NLO crystals into big high-high quality types or into quasi-phase-matching buildings which have been suited to the laser gadgets by many expansion methods and Checking out new probable mid-IR NLO crystals by introducing new style and synthesis methods.
Distinction frequency mixing of strongly targeted Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been targeted inside the crystal with out damage. Mixing of cw and pulsed laser systems was used to reduce the thermal lensing effects inside of this crystal. A small-electric power cw one.064‐μm Nd:YAG laser beam was utilised as the pump, While the sign beam came from the picosecond optical .
