053 μm. The absorption spectrum of ammonia was offered to show the feasibility of your formulated optical parametric oscillator technique for spectroscopic measurements and gas detection.
We report with a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) dependant on the Kerr-lens-manner-locked Ti:sapphire laser since the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO dependant on the nonlinear crystal, CdSiP 2 , synchronously pumped internal to some MgO:PPLN femtosecond OPO, We now have created broadly tunable radiation throughout 5958�?117 nm applying immediate static cavity hold off tuning, with a optimum electricity of sixty four μW at 6791 nm, restricted because of the absorption in mirror substrates and also polarization-dependent intracavity losses.

Reports of practical pump laser technologies appropriate for ultrafast femtosecond OPOs based upon CdSiP 2 are talked about, and the favorable linear and nonlinear optical properties, and also exclusive stage-matching properties of CdSiP 2 , are introduced employing The newest Sellmeier equations for the fabric. The explained experimental effects symbolize the highest output pulse Power and history regular electricity from the ultrafast picosecond and femtosecond time scales over the six–7 μm spectral array so far.
Within this do the job, we existing exactly what is, to our know-how, the very first measurements with the quantum section diffusion sounds of a cw OPO. Examine more
The significant conversion performance and wide selection of radiation wavelength tuning allows to hope that this product may well contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the significant problem of big measurement crystals development procedure.
The temperature dependence of refractive indices of optical supplies is characterized During this work by what we contact their normalized thermo-optic coefficients. They're determined experimentally as a result of interferometric measurements of thermal enlargement and of changes in optical thickness at a few laser wavelengths as operate of temperature. An acceptable vectorial formalism placed on these info allows predicting the thermal evolution in the refractive index all around the valuable choice of transparency.
We existing a numerical study for the look of productive MgO:PPLN based mostly pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top-hat transverse depth profile, and a double-move pump cavity configuration. Especially, we look into the influence of domain condition to the conversion efficiency. We considered two sorts of domain buildings: "ideal vertical-wall" and "wedge-shaped" domains and our numerical outcomes present that at better pump pulse energies, the conversion website performance saturates, as well as saturated effectiveness is nearly unbiased of the domain designs.
Additionally, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed which the spectral profile of your output from a CPOPO was applicable to the two the parametric get profile from the nonlinear crystal and the intra-cavity significant-get dispersion.
stabilize and tune the OPO, from which the reliable etalon gave a better effectiveness. Temperature oscillations within the PPLN crystal
Interference is noticed concerning the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser system. By employing a 300 μm lengthy magnesium-doped periodically poled LiNbO three crystal given that the parametric acquire medium and configuring the OPO being a chirped-pulse oscillator, we obtained mid-infrared emission possessing an instantaneous bandwidth covering 3084�?466 nm. This consequence signifies, to the top of our know-how, the widest instantaneous bandwidth obtained from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the huge opportunity of chirped-pulse oscillation in scaling the instantaneous bandwidth of extremely-rapidly OPOs.
A simple quantum product agrees properly Together with the experimental results and causes it to be attainable to interpret the result with regards to
