Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAs
The significance of your attained effects lies in The truth that to find the exact same conversion in SHG or DFM, a person now necessitates essential enter radiation with Significantly reduced depth.

By employing intracavity dispersion control, in close proximity to-transform-minimal sign pulses of �?one hundred fs period with smooth solitary-peak spectrum are accomplished at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the ideal of our awareness, This can be The 1st time this sort of realistic idler powers in the deep-IR are already created from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition fee.
We report new experimental success around the section-matching Homes of yellow colour HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers from the 0.944-10.5910 μm vary. Also, we present new Sellmeier equations that provide a superior reproduction on the current experimental results in addition to the posted information details for 2nd-harmonic era of CO2 laser radiation at 9.
triggered oscillations while in the idler wavelength of under 200MHz in excess of 300s; the limited-time period steadiness was less than 3MHz
The technology of tunable pico- and femtosecond light-weight pulses with parametric frequency conversion procedures has attracted enhanced awareness recently1. New crystal elements, as BBO, LBO, and KTP, with exceptional nonlinearity and substantial problems threshold are actually readily available, and pump lasers of enhanced steadiness enable the responsible Procedure of optical parametric oscillators. Parametric equipment pumped ... [Show entire summary] both by cw modelocked lasers or by solitary intensive ultrashort pulses happen to be produced. With this contribution parametric techniques are mentioned which might be pumped by powerful pulse trains of a few microseconds duration and repetition fees as many as 50Hz.
A way is designed to unravel the technique of shortened equations describing parametric technology within a one-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well as the best reflection coefficient from the output mirror are approximated as opposed to the pump energy density Wp at unique values from the OPO nonstationarity .

... The very first facts around the refractive index of orange HGS released by Levine et al. [35] included only handful of wavelengths during the noticeable and in close proximity to-IR equally as an illustration from the feasibility of the crystal for birefringent stage-matching. The refractive indices with the orange phase have been measured and tabulated involving 0.
gas analyzers is carried out. The click here designed PA methane sensor is customized for placement within the UAV’s board. Unit
In this particular paper we theoretically examine one of the most productive pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Examination includes resolving the ideal Manage trouble using the rate equation formalism. The OPO best buildup conduct is derived for any OPO configuration, and we exhibit that the exceptional pump pulse form is a double rectangle. The initial rectangle is optimized with the buildup procedure, whilst the next one particular is optimized with the continuous state, and the two depend otherwise around the OPO mirror reflectivities together with the accessible pump Strength and most peak electrical power.
This is the initial example of a broadband OPO working over the molecular fingerprint location, and we reveal its potential by conducting broadband Fourier-remodel spectroscopy making use of drinking water vapor plus a polystyrene reference common.
