053 μm. The absorption spectrum of ammonia was offered to display the feasibility of the produced optical parametric oscillator process for spectroscopic measurements and gas detection.
It has lengthy been predicted the phase distinction between the sign and idler subharmonic outputs of an optical parametric oscillator (OPO) undergoes a random wander system, similar to the period diffusion of a laser [1].
A list of ~450 noncentrosymmetric sulfides has long been noticed in reference to nonlinear optical Attributes. It has been found that on the plane with the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
A straightforward procedure for reducing the reduction that is due to depolarization resulting from thermally induced pressure birefringence in strong-point out lasers is described. The procedure works by using just one intracavity quarter-wave plate with its quickly or slow axis aligned parallel to the preferred plane of polarization, outlined by an intracavity polarizer.
OPO ended up improved by optimizing pump beam waist and OPO cavity size. Each air-spaced and reliable etalons had been analyzed to frequency
This double rectangle is quantitatively described and is also in step with former outcomes described during the literature. Also, numerical simulations are accustomed to validate our analytical product over a doubly resonant OPO and present dependable effects. The numerical simulations also demonstrate that an optimal top rated-hat temporal profile could supply performances really near to the ones attained While using the exceptional double rectangle.
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are studied utilizing perturbation concept beneath the ailment of rotating wave approximation. The 2 parametric FWM processes are coupled when they're energized coherently by a short laser pulse having a bandwidth encompassing The 2 corresponding upper Electrical power degrees in The 2 FWM procedures.
We current a numerical review for the look of efficient MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of top-hat transverse intensity profile, along with a double-pass pump cavity configuration. Especially, we investigate the result of area condition to the conversion efficiency. We viewed as two types of domain structures: "best vertical-wall" and "wedge-formed" domains and our numerical success display that at larger pump pulse energies, the conversion efficiency saturates, and also the saturated effectiveness is sort of impartial of the domain shapes.
Solid state polymerization of diacetylenes The crystal structure of HAlSi2O6 by using a keatite-sort framework Syntheses and crystal buildings of α
Investigation of new, promising vast-band-gap nonlinear crystals for the mid-IR is offered. We focused on ternary and quaternary chalcogenides and primarily based on their own Bodily and chemical Houses, which As well as linear and nonlinear optical Homes, figure out the efficiency of crystal use in sure laser experiments. The correlation concerning the composition, construction and output parameters and also the tendencies in modifications of the leading attributes for instance band gap, nonlinear susceptibility, laser problems threshold, and many others, are shown.
... The very first knowledge within the refractive index of orange HGS published by Levine et al. [35] included only number of wavelengths from the visible and around-IR just as a demonstration of your feasibility of the crystal for birefringent stage-matching. The refractive indices for your orange phase ended up calculated and tabulated amongst 0.
Quantum mechanical centered to start with basic principle calculations happen to be employed to acquire the device mobile lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite structure for The read more very first time. For this, we handled HgGa2S4 in two different types of web site symmetries in the identical Place group.
A simple quantum model agrees well While using the experimental success and makes it achievable to interpret the effect with regard to
Tunable mid-IR radiation is acquired for the duration of second harmonic era of tunable CO2-laser radiation employing a CdGeAs2 crystal. Its angular tuning features within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
