Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR variance-frequency generation in OPGaAs
Output idler energies around the microjoule amount are received with most conversion effectiveness of 11% for that amplifier phase, which happens to be a lot more than two times much better than the effects received with the analogous sample from the extensively unfold materials AgGaS 2 .

.. [Clearly show entire abstract] 3rd-harmonic generation and parametric amplification with small-frequency pumping in periodically poled Energetic nonlinear crystals may also be investigated. The Investigation is completed for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Views of employing periodically poled active nonlinear crystals in laser products with self-frequency conversion are talked over.
from the laser emission wavelength. The minimal measured qualifications signal on the PA sensor (working with substantial purity
The high conversion performance and wide range of radiation wavelength tuning permits to count on that this substance may perhaps contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the significant trouble of huge size crystals growth system.
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are studied working with perturbation principle underneath the problem of rotating wave approximation. The two parametric FWM procedures are coupled when they're excited coherently by a brief laser pulse that has a bandwidth encompassing The 2 corresponding upper Power amounts in The 2 FWM processes.
A method is designed to resolve the procedure of shortened equations describing parametric era in a one particular-frequency OPO cavity under nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals along with the optimum reflection coefficient on the output mirror are approximated versus the pump Electricity density Wp at distinct values of the OPO nonstationarity .
Vibrational spectra of Li-made up of nonlinear crystals and their application in THz radiation era are discussed. Using an example of LiGaS2, the defect effect on spectroscopic characteristics is proven. Superior-temperature annealing in a proper environment allows one particular to remove prolonged and position defects and also to Increase the transparency. Vitality composition and parameters of principal point defects for instance anion vacancy (File-Heart) and cation antisite defect GaLi calculated from the primary rules concur properly with the experimental results.

Interference is observed in between the spontaneous parametric radiation from two nonlinear crystals separated by a macroscopic
12 μm and describe all frequency conversion techniques understood to date with them as well as potential opportunity applications. Key phrases: Ternary and quaternary semiconductors, defect chalcopyrites, sound alternatives, nonlinear optical crystals, mid-infrared
Single-step sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Diode-pumped optical parametric oscillation continues to be demonstrated for The 1st time to our information in only one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions soak up the 812-nm radiation to deliver here 1084-nm laser oscillation.
