Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR distinction-frequency generation in OPGaAs
It has prolonged been predicted the phase difference between the signal and idler subharmonic outputs of the optical parametric oscillator (OPO) undergoes a random walk process, much like the phase diffusion of a laser [1].

By utilizing intracavity dispersion Management, close to-transform-minimal signal pulses of �?a hundred fs duration with smooth solitary-peak spectrum are accomplished at 1264 nm, comparable to an idler wavelength at 6440 nm. To the most effective of our knowledge, This is certainly the first time these sensible idler powers during the deep-IR have already been created from a dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition level.
During this work, we present exactly what is, to our information, the primary measurements on the quantum stage diffusion noise of a cw OPO. Read more
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it may be consistently tuned from 1.261 by way of two.532 μm by different the pump wavelength. Two major improvements have been realized, such as the relationship in the sign and idler tuning ranges as well as the large output pulse Electricity throughout the sign and idler tuning ... [Show total abstract] ranges. The 1st improvement was attained by exploring two certain sets of period-matching angles. The 2nd advancement was understood by making use of five sets of resonator mirrors for oscillating either signal or idler.
The temperature dependence of refractive indices of optical components is characterized Within this perform by what we contact their normalized thermo-optic coefficients. They're established experimentally by interferometric measurements of thermal enlargement and of changes in optical thickness at a number of laser wavelengths as purpose of temperature. An appropriate vectorial formalism applied to these data lets predicting the thermal evolution on the refractive index all over the valuable choice of transparency.
air hole and enthusiastic in sequence by a common pump beam. The section of your interference depends on the section shifts at a few frequencies.
Better-purchase nonlinear processes in different elements will also be regarded as in addition to a discussion on product suitability for down-conversion of in close proximity to-IR lasers in to the mid-IR to fulfill a variety of application needs is additionally introduced.
The technologies of growing mercury thiogallate crystals (HgGa2S4) is improved and large-high quality bulk samples are created. The basic optical and thermal Houses of such crystals are analyzed. The transmission spectra of mercury thiogallate are measured and its nonlinear attributes including the quadratic susceptibility, tuning curves, and the optical-injury resistance also are identified.
The defect chalcopyrite crystal HgGa2S4 is employed inside a 1064-nm pumped optical parametric oscillator to produce Nonlinear crystals for optical parametric oscillators pumped by light-weight pulses of in the vicinity of IR lasers...
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser program. By employing a three hundred μm extended magnesium-doped periodically poled LiNbO 3 crystal as the parametric obtain medium and configuring the OPO as being a chirped-pulse oscillator, we obtained mid-infrared emission obtaining an instantaneous bandwidth masking 3084�?466 nm. This consequence represents, to the most beneficial of our knowledge, the widest instantaneous bandwidth received from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous possible of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-quick OPOs.
In this paper we theoretically look into by far the most productive pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Evaluation consists of fixing the optimum Command dilemma using the amount equation formalism. The here OPO optimum buildup actions is derived for just about any OPO configuration, and we show which the optimum pump pulse condition is actually a double rectangle. The main rectangle is optimized to the buildup process, even though the second one particular is optimized for the constant point out, and the two count in another way on the OPO mirror reflectivities together with the available pump Strength and most peak electrical power.
.. [Display comprehensive summary] bandwidth. Experimental final results exhibiting entanglement era with significant costs along with a comparison into the very well investigated β-BaB2O4 (BBO) crystal are presented in addition. Shifting the down-conversion crystal of a polarization entangled photon supply from BBO to BiBO enhances the era rate as If your pump electrical power was amplified by 2.five instances. These types of an enhancement is now demanded to the generation of multiphoton entangled states.
