and operating conditions for the sensible design and style of large energy femtosecond optical parametric oscillators with excitation
Benefits of thermal conductivity measurements are noted for a number of of the greater a short while ago developed nonlinear optical crystals. New or significantly revised values of thermal conductivity were being attained in 6 products. Notable thermal conductivities calculated were All those for AgGaS2 [0.014 W/(cm K) and 0.

By implementing intracavity dispersion Manage, in close proximity to-completely transform-constrained signal pulses of �?100 fs length with smooth solitary-peak spectrum are attained at 1264 nm, similar to an idler wavelength at 6440 nm. To the most effective of our understanding, this is The very first time these types of useful idler powers during the deep-IR have already been produced from a dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition price.
of your laser emission wavelength. The least measured track record signal of your PA sensor (making use of substantial purity
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it may be continuously tuned from one.261 by way of two.532 μm by different the pump wavelength. Two main enhancements ended up achieved, including the relationship in the sign and idler tuning ranges and also the substantial output pulse energy with the sign and idler tuning ... [Clearly show complete summary] ranges. The main improvement was accomplished by exploring two particular sets of stage-matching angles. The next enhancement was understood through the use of 5 sets of resonator mirrors for oscillating possibly sign or idler.
The temperature dependence of refractive indices of optical components is characterised in this perform by what we call their normalized thermo-optic coefficients. They're decided experimentally by interferometric measurements of thermal enlargement and of changes in optical thickness at a couple of laser wavelengths as operate of temperature. An appropriate vectorial formalism placed on these details allows predicting the thermal evolution from the refractive index all around the beneficial variety of transparency.
We existing a numerical review for the look of productive MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of prime-hat transverse intensity profile, and a double-go pump cavity configuration. Specifically, we examine the outcome of domain condition about the conversion efficiency. We viewed as two forms of domain structures: "fantastic vertical-wall" and "wedge-shaped" domains and our numerical results exhibit that at larger pump pulse energies, the conversion efficiency saturates, along with the saturated efficiency is nearly unbiased in the area shapes.

stabilize and tune the OPO, from which the sound etalon gave a greater functionality. Temperature oscillations from the PPLN crystal
... The very first knowledge on the refractive index of orange HGS released by Levine et al. [35] included only number of wavelengths during the visible and in close proximity to-IR equally as a demonstration on the feasibility of the crystal for birefringent phase-matching. The refractive indices for that orange phase had been more info calculated and tabulated concerning 0.

The chosen nonlinear crystals exhibit better nonlinear conversion efficiency in comparison to AgGaS two , with BaGa 2 GeS 6 additionally giving a narrower angular spectrum of spontaneous parametric down conversion, advantageous in interferometric strategies. Our conclusions set up a pathway for integrating Highly developed crystal technologies into mid-infrared metrology and imaging devices, setting the stage for foreseeable future developments in nonlinear interferometry and spectroscopy.
Diode-pumped optical parametric oscillation has actually been demonstrated for The very first time to our knowledge in just one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take up the 812-nm radiation to generate 1084-nm laser oscillation.
