HgGa2S4 Crystal Options
and running ailments for the sensible style and design of superior energy femtosecond optical parametric oscillators with excitationA method-locked tunable dye laser has become produced which is synchronously pumped at large repetition fees via the doubled output of a manner-locked Nd:YAG laser. The dye laser supplies intensive pulses of 35 psec duration which can be widely tunable, of near-renovate-restricted bandwidth, As well as in time coincidence with the pumping pulses.
crystals with ultrafast Yb-ion laser pump is proposed. The results form a valuable reference for the choice of products
Reports of viable pump laser systems suitable for ultrafast femtosecond OPOs according to CdSiP two are talked about, as well as favorable linear and nonlinear optical properties, in addition to exclusive period-matching qualities of CdSiP two , are introduced using The newest Sellmeier equations for the material. The described experimental results represent the highest output pulse Strength and report normal electricity within the ultrafast picosecond and femtosecond time scales through the six–7 μm spectral range to date.
OPO have been improved by optimizing pump beam midsection and OPO cavity size. Both air-spaced and sound etalons were examined to frequency
The measured core stage binding energies are in contrast with Individuals of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to become unbiased within the technological situations of crystal growth. In contrast towards the valence band spectrum, the distribution of electron states in the bandgap of HgGa2S4 crystals is found to be strongly dependent on the technological disorders of crystal development as shown via the photoluminescence Investigation.
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are analyzed working with perturbation concept beneath the issue of rotating wave approximation. The 2 parametric FWM procedures are coupled when they're psyched coherently by a brief laser pulse that has a bandwidth encompassing The 2 corresponding higher Strength concentrations in The 2 FWM processes.
Pumping mid-IR optical parametric oscillators close to one μm is interesting for its simplicity and electricity scaling capacity. To this goal, broad bandgap non-oxide nonlinear crystals are required.
Additionally, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and exposed that the spectral profile of your output from the CPOPO was applicable to equally the parametric achieve profile of the nonlinear crystal as well as the intra-cavity substantial-get dispersion.
The technological know-how of increasing mercury thiogallate crystals (HgGa2S4) is improved and high-quality bulk samples are developed. The fundamental optical and thermal Qualities of those crystals are researched. The transmission spectra of mercury thiogallate are calculated and its nonlinear properties like the quadratic susceptibility, tuning curves, along with the optical-injury resistance can also be identified.
... The very first knowledge on the refractive index of orange HGS released by Levine et al. [35] incorporated only handful of wavelengths while in the noticeable and in the vicinity of-IR equally as an indication of your feasibility of the crystal for birefringent section-matching. The refractive indices for that orange stage had been measured and tabulated amongst 0.
for your detection of molecular trace gasses. The oscillation threshold, output ability and security of the single resonant
During this paper we theoretically investigate essentially the most economical pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Investigation is made up of resolving the optimal Command difficulty utilizing the price equation formalism. The OPO optimal buildup behavior is derived for any OPO configuration, and we exhibit the exceptional pump pulse shape is actually a double rectangle. The primary rectangle is optimized for your buildup approach, although the second a person is optimized for that steady state, and both count differently over the OPO mirror reflectivities as well as the available pump Power and utmost peak energy.
Tunable mid-IR radiation is attained during second harmonic technology of tunable CO2-laser radiation employing a CdGeAs2 crystal. Its angular tuning attributes for the CO2- more info laser wavelength, angular acceptance angle and spectral acceptance are calculated.
