With the advent of recent nonlinear components and one-frequency pump resources, There is certainly renewed curiosity in optical parametric oscillators (OPOs). One-manner diode-laser-pumped monolithic Nd:YAG nonplanar ring laser which is equally amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
A manner-locked tunable dye laser has become produced which can be synchronously pumped at high repetition prices through the doubled output of the manner-locked Nd:YAG laser. The dye laser supplies intense pulses of 35 psec period which might be extensively tunable, of near-renovate-constrained bandwidth, As well as in time coincidence Together with the pumping pulses.

By applying intracavity dispersion control, in close proximity to-change-confined sign pulses of �?100 fs length with easy one-peak spectrum are reached at 1264 nm, equivalent to an idler wavelength at 6440 nm. To the very best of our expertise, This is often The very first time this sort of practical idler powers while in the deep-IR are already generated from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition charge.
During this work, we existing what exactly is, to our information, the first measurements on the quantum phase diffusion sounds of a cw OPO. Examine much more

The temperature dependence of refractive indices of optical resources is characterised Within this perform by what we simply call their normalized thermo-optic coefficients. They are established experimentally by way of interferometric measurements of thermal enlargement and of changes in optical thickness at a couple of laser wavelengths as perform of temperature. An acceptable vectorial formalism placed on these details allows predicting the thermal evolution in the refractive index all around the handy range of transparency.
A way is developed to resolve the procedure of shortened equations describing parametric era in a very one-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals and also the ideal reflection coefficient of your output mirror are estimated as opposed to the pump Electricity density Wp at distinct values with the OPO nonstationarity .

... The initial details around the refractive index of orange HGS released by Levine et al. [35] included only handful of wavelengths during the visible and around-IR equally as an indication of the feasibility of this crystal for birefringent stage-matching. The refractive indices for that orange stage were measured and tabulated in between 0.
Quantum mechanical dependent to start with basic principle calculations have been utilized read more to obtain the device cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite structure for the first time. For this, we treated HgGa2S4 in two differing types of web-site symmetries in the same House team.
On this paper we theoretically look into quite possibly the most successful pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Evaluation is made of fixing the optimal Regulate issue utilizing the level equation formalism. The OPO ideal buildup behavior is derived for almost any OPO configuration, and we display which the optimum pump pulse condition is actually a double rectangle. The first rectangle is optimized to the buildup process, even though the second one particular is optimized for your regular point out, and both count differently to the OPO mirror reflectivities along with the offered pump energy and highest peak ability.
Tunable mid-IR radiation is attained throughout 2nd harmonic era of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning properties in the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
