Based upon our examine, we also propose a whole new plan for growth of compact high-electrical power OPO sources making use of MgO:PPLN chips of fairly limited lengths and large cross-sectional area.

Benefits of thermal conductivity measurements are reported for many of the more not long ago developed nonlinear optical crystals. New or significantly revised values of thermal conductivity were being obtained in six supplies. Noteworthy thermal conductivities measured were being These for AgGaS2 [0.014 W/(cm K) and 0.

The main-concepts density useful calculations are performed to study the geometries and Digital structures of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, along with the optical Attributes of all crystals are investigated systematically. The final results reveal that these compounds have related band buildings plus the band hole decreases from S to Se to Te. For your linear optical Houses, 3 crystals clearly show fantastic mild transmission within the IR and part visible regions, and specifically, HgGa2S4 and HgGa2Se4 crystals have average birefringence.

A straightforward approach for cutting down the loss that is due to depolarization ensuing from thermally induced worry birefringence in reliable-point out lasers is reported. The technique uses an individual intracavity quarter-wave plate with its quick or gradual axis aligned parallel to the preferred aircraft of polarization, described by an intracavity polarizer.

We report new experimental results within the period-matching Attributes of yellow color HgGa2S4 crystals for harmonic technology of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers within the 0.944-10.5910 μm range. Moreover, we current new Sellmeier equations that offer a good replica with the current experimental benefits together with the printed facts points for 2nd-harmonic generation of CO2 laser radiation at nine.

The calculated Main stage binding energies are when compared with All those of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves to generally be impartial within the technological circumstances of crystal development. In distinction towards the valence band spectrum, the distribution of electron states during the bandgap of HgGa2S4 crystals is discovered to become strongly dependent on the technological problems of crystal expansion as demonstrated from the photoluminescence Evaluation.

Although making use of an institutional account for this Web site we don’t keep track of any personal, overall performance, purposeful or 1st or 3rd get together connected data.

We existing a numerical analyze for the look of efficient MgO:PPLN centered pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of top rated-hat transverse depth profile, and also a double-move pump cavity configuration. Particularly, we look into the impact of area condition within the conversion efficiency. We viewed as two forms of domain constructions: "ideal vertical-wall" and "wedge-formed" domains and our numerical outcomes clearly show that at larger pump pulse energies, the conversion efficiency saturates, and the saturated effectiveness is nearly independent on the domain designs.

Vibrational spectra of Li-that contains nonlinear crystals and their application in THz radiation era are talked about. Using an example of LiGaS2, the defect effect on spectroscopic properties is demonstrated. Higher-temperature annealing in a proper ambiance lets a person to remove extended and place defects and also to Enhance the transparency. Energy construction and parameters of primary issue defects which include anion vacancy (F-Middle) and cation antisite defect GaLi calculated from the primary concepts concur click here nicely with the experimental success.

Very simple method for cutting down the depolarization decline resulting from thermally induced birefringence in reliable-state lasers

The observed file -to- two file frequency beats, originating straight from the OPO, can be used for self-referencing and section locking on the pump laser comb with no need for supercontinuum technology. With a median output energy of �?30 mW , this set up could possibly be helpful for several different spectroscopic purposes from the mid-IR.

In this particular paper we theoretically look into one of the most productive pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Investigation is made of fixing the optimum Manage trouble utilizing the fee equation formalism. The OPO ideal buildup conduct is derived for any OPO configuration, and we demonstrate the optimal pump pulse form is usually a double rectangle. The primary rectangle is optimized for the buildup method, when the second 1 is optimized to the constant state, and both of those depend in a different way within the OPO mirror reflectivities together with the available pump energy and maximum peak power.

Diode-pumped optical parametric oscillation has been shown for The 1st time to our know-how in one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take in the 812-nm radiation to make 1084-nm laser oscillation.
