and running circumstances for the sensible design of high electric power femtosecond optical parametric oscillators with excitation
Output idler energies within the microjoule level are received with highest conversion performance of 11% to the amplifier stage, which can be over two situations much better than the effects attained by having an analogous sample with the greatly distribute content AgGaS two .

The higher conversion effectiveness and wide selection of radiation wavelength tuning will allow to hope this content may possibly compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the sizeable issue of big size crystals advancement course of action.
of the laser emission wavelength. The minimum calculated qualifications sign of the PA sensor (using significant purity
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Together with sign and idler, it may be repeatedly tuned from one.261 through 2.532 μm by various the pump wavelength. Two significant improvements were being accomplished, including the relationship from the sign and idler tuning ranges as well as the superior output pulse Electricity in the signal and idler tuning ... [Exhibit complete summary] ranges. The first advancement was realized by exploring two distinct sets of section-matching angles. The next enhancement was recognized by using five sets of resonator mirrors for oscillating either sign or idler.
The temperature dependence of refractive indices of optical supplies is characterised On this perform by what we get in touch with their normalized thermo-optic coefficients. They're established experimentally through interferometric measurements of thermal enlargement and of variations in optical thickness at a couple of laser wavelengths as functionality of temperature. A suitable vectorial formalism placed on these info enables predicting the thermal evolution of the refractive index all over the handy array of transparency.
Dependant on the theories of phase matching and appropriate composition ratio, the affect of composition ratio over the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thing to consider of corresponding sellmeier equations, phase matching diagrams of second harmonic generation and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers were calculated, and suitable composition ratios with several compositions.

Interference is observed between the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
12 μm and describe all frequency conversion techniques realized to this check here point with them together with upcoming possible programs. Keywords: Ternary and quaternary semiconductors, defect chalcopyrites, reliable solutions, nonlinear optical crystals, mid-infrared
During this paper we theoretically examine essentially the most economical pump temporal form for pulsed operation of optical parametric oscillators (OPOs). The theoretical Assessment is made of resolving the exceptional Regulate difficulty utilizing the rate equation formalism. The OPO ideal buildup actions is derived for just about any OPO configuration, and we exhibit the exceptional pump pulse shape can be a double rectangle. The 1st rectangle is optimized for your buildup approach, although the second a person is optimized for your continual state, and both of those count otherwise about the OPO mirror reflectivities and also the out there pump Electricity and highest peak ability.
three% rms around twelve h in great beam high quality. The close to-IR signal pulses with the OPO Have a very Gaussian pulse length of �?19 ps , measured at 1284 nm. We've got investigated the temperature tuning attributes in the OPO and when compared the info Using the theoretical calculations utilizing the most recent Sellmeier equations and thermo-optic coefficients to the crystal. To the very best of our expertise, this is the initially picosecond OPO depending on CSP working at MHz repetition charges.
