Optical parametric oscillator pumped at ~one µm with intracavity mid-IR variance-frequency technology in OPGaAs
A method-locked tunable dye laser has become produced which is synchronously pumped at higher repetition fees through the doubled output of the method-locked Nd:YAG laser. The dye laser delivers intensive pulses of 35 psec period which are greatly tunable, of near-rework-confined bandwidth, and in time coincidence Using the pumping pulses.
The initial-ideas density practical calculations are performed to study the geometries and Digital constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite structures, and also the optical Attributes of all crystals are investigated systematically. The effects suggest that these compounds have related band structures and the band gap decreases from S to Se to Te. For your linear optical Attributes, 3 crystals demonstrate very good light-weight transmission while in the IR and element noticeable regions, and in particular, HgGa2S4 and HgGa2Se4 crystals have reasonable birefringence.
In both equally the cases attained device cell parameters are identical, which shows the accuracy of current approach. The Digital band buildings clearly show the semiconducting behavior in equally the scenarios. The density of states plot will also be researched and talked about.
We report new experimental outcomes about the stage-matching Homes 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-ten.5910 μm range. Also, we existing new Sellmeier equations that offer a great reproduction with the current experimental benefits as well as the released information details for 2nd-harmonic era of CO2 laser radiation at 9.
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Together with sign and idler, it could be continually tuned from 1.261 by way more info of two.532 μm by different the pump wavelength. Two significant improvements have been achieved, including the relationship from the signal and idler tuning ranges and also the superior output pulse Strength from the sign and idler tuning ... [Display total abstract] ranges. The initial improvement was reached by getting two individual sets of section-matching angles. The 2nd improvement was realized through the use of 5 sets of resonator mirrors for oscillating both signal or idler.
Optical properties of orange phased HgGa2S4 crystal is investigated. Generation of tunable Center infrared radiation by second harmonic of tunable CO2 laser radiation has actually been demonstrated. 2nd harmonic conversion performance with regard to other infrared crystal has also been discussed.
Pumping mid-IR optical parametric oscillators close to one μm is desirable for its simplicity and energy scaling capacity. To this intention, broad bandgap non-oxide nonlinear crystals are required.

The third harmonic of CO2-laser radiation has long been acquired by passing the laser beam via two CdGeAs2 crystals in tandem, with the first crystal oriented for second-harmonic era and the 2nd for sum mixing. Applying This method, We now have realized a mean external conversion effectiveness of one.
Straightforward process for decreasing the depolarization loss resulting from thermally induced birefringence in stable-point out lasers
gasoline analyzers is completed. The made PA methane sensor is tailored for placement over the UAV’s board. Unit
A pulsed TEA CO2 laser was employed to investigate the result of pump radiation parameters (manner composition, wavelength, and pulse length), focusing disorders, absorption coefficient, and temperature over the efficiency of conversion into the 2nd harmonic and on angular dependences of stage matching in ZnGeP2 crystals. Good agreement betweeen experimental and theoretical results is observed. Browse a lot more
3% rms around 12 h in fantastic beam top quality. The in the vicinity of-IR sign pulses from your OPO Have a very Gaussian pulse length of �?19 ps , calculated at 1284 nm. We have now investigated the temperature tuning attributes on the OPO and when compared the data While using the theoretical calculations making use of The newest Sellmeier equations and thermo-optic coefficients for your crystal. To the most effective of our expertise, This can be the initially picosecond OPO depending on CSP working at MHz repetition rates.
