053 μm. The absorption spectrum of ammonia was introduced to demonstrate the feasibility of your created optical parametric oscillator program for spectroscopic measurements and fuel detection.
We report over a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) based on the Kerr-lens-mode-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP 2 , synchronously pumped inside to your MgO:PPLN femtosecond OPO, Now we have produced broadly tunable radiation across 5958�?117 nm making use of speedy static cavity hold off tuning, which has a greatest electrical power of 64 μW at 6791 nm, confined from the absorption in mirror substrates and polarization-dependent intracavity losses.
crystals with ultrafast Yb-ion laser pump is proposed. The outcome kind a beneficial reference for the selection of materials
By utilizing intracavity dispersion control, near-completely transform-restricted signal pulses of �?a hundred fs duration with clean single-peak spectrum are realized at 1264 nm, akin to an idler wavelength at 6440 nm. To the top of our expertise, This is often The very first time this kind of practical idler powers within the deep-IR are already produced from the dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition fee.
With this work, we existing precisely what is, to our awareness, the initial measurements of the quantum stage diffusion sound of the cw OPO. Read through extra
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Such as signal and idler, it may be consistently tuned from 1.261 through 2.532 μm by varying the pump wavelength. Two key advancements had been reached, such as the connection on the sign and idler tuning ranges as well as the significant output pulse Power throughout the sign and idler tuning ... [Clearly show complete abstract] ranges. The main advancement was obtained by discovering two specific sets of stage-matching angles. The next enhancement was recognized through the use of 5 sets of resonator mirrors for oscillating both sign or idler.
The temperature dependence of refractive indices of optical materials is characterised In this particular do the job by what we get in touch with their normalized thermo-optic coefficients. These are typically determined experimentally via interferometric measurements of thermal enlargement and of changes in optical thickness at a few laser wavelengths as operate of temperature. An appropriate vectorial formalism placed on these details enables predicting the thermal evolution of your refractive index all over the beneficial choice of transparency.
We current a numerical review for click here the design of economical MgO:PPLN based mostly pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top rated-hat transverse intensity profile, in addition to a double-pass pump cavity configuration. Particularly, we look into the influence of area condition within the conversion performance. We deemed two varieties of area constructions: "perfect vertical-wall" and "wedge-formed" domains and our numerical final results show that at better pump pulse energies, the conversion efficiency saturates, and the saturated effectiveness is almost impartial of the domain styles.

Interference is noticed concerning the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
Observe: Creator names might be searched within the key terms discipline, also, but which will locate papers wherever the person is talked about, rather then papers they authored.
The latest mid-IR NLO crystals is usually divided into four classes, i.e., classical binary and ternary steel pnictides and chalcogenides, quaternary metallic chalcogenides, binary and ternary metal halides, and different-bond-variety hybrid compounds that consist of at the very least two forms of certainly different chemical bonds within the crystal constructions. Metal pnictides and chalcogenides have received Considerably notice on increasing substantial crystals. Distinct-bond-type hybrid is a whole new spouse and children of mid-IR NLO components, and several of them were present in the final decade. In steel halide method, both development in escalating large crystals and finding new ones are actually manufactured.
.. [Clearly show whole abstract] bandwidth. Experimental outcomes demonstrating entanglement era with higher charges and a comparison into the very well investigated β-BaB2O4 (BBO) crystal are presented as well. Transforming the down-conversion crystal of a polarization entangled photon resource from BBO to BiBO improves the era amount as Should the pump electricity was elevated by two.5 situations. These kinds of an improvement is now necessary for the era of multiphoton entangled states.
