With the advent of latest nonlinear materials and single-frequency pump resources, there is renewed interest in optical parametric oscillators (OPOs). An individual-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely each amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
We report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) dependant on the Kerr-lens-method-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP two , synchronously pumped interior to some MgO:PPLN femtosecond OPO, We have now created broadly tunable radiation across 5958�?117 nm utilizing fast static cavity hold off tuning, having a highest electric power of sixty four μW at 6791 nm, confined via the absorption in mirror substrates as well as polarization-dependent intracavity losses.
The primary-concepts density useful calculations are carried out to study the geometries and electronic buildings of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite buildings, as well as optical Houses of all crystals are investigated systematically. The outcomes show that these compounds have similar band buildings plus the band hole decreases from S to Se to Te. For that linear optical Homes, a few crystals show great gentle transmission from the IR and portion seen locations, and specifically, HgGa2S4 and HgGa2Se4 crystals have average birefringence.
In both equally the instances received device mobile parameters are same, which exhibits the accuracy of current tactic. The electronic band constructions exhibit the semiconducting behavior in the two the conditions. The density of states plot are researched and discussed.
On this perform, we present what exactly is, to our expertise, the 1st measurements of the quantum stage diffusion sound of the cw OPO. Browse more
The substantial conversion performance and wide range of radiation wavelength tuning permits to hope this materials could compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Regardless of the considerable difficulty of huge measurement crystals expansion course of action.
The temperature dependence of refractive indices of optical components is characterized in this do the job by what we contact their normalized thermo-optic coefficients. They are decided experimentally as a result of interferometric measurements of thermal expansion and of adjustments in optical thickness at a number of laser wavelengths as purpose of temperature. An acceptable vectorial formalism applied to these facts allows predicting the thermal evolution with the refractive index everywhere in the beneficial array of transparency.
air hole and energized in sequence by a typical pump beam. The phase of the interference depends upon the section shifts at a few frequencies.
The particular heat and thermal conductivity of HgGa2S4 are measured. It is concluded which the merged Homes of HgGa2S4 crystals can offer for them a leading place among the elements Utilized in nonlinear-optical devices for mid-IR-frequency conversion.
The technology of developing mercury thiogallate crystals (HgGa2S4) is enhanced and significant-excellent bulk samples are made. The essential optical and thermal Qualities of these crystals are researched. The transmission spectra of mercury thiogallate are calculated and its nonlinear characteristics like the quadratic susceptibility, tuning curves, and also the optical-problems resistance also are determined.
Straightforward system for decreasing the depolarization decline ensuing from thermally induced birefringence in strong-condition lasers
Quantum mechanical dependent to start with basic principle calculations have already been employed to acquire the device cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite framework for the first time. For this, we dealt with HgGa2S4 in two different types of web site symmetries in a similar Place group.
One-action sub-two hundred fs mid-infrared generation from an optical parametric oscillator synchronously pumped by an erbium fiber laser
This is the initial illustration of a broadband OPO working through the molecular fingerprint area, and we exhibit its possible by conducting broadband Fourier-rework spectroscopy applying water vapor as more info well as a polystyrene reference common.
