and operating ailments for the practical style of significant ability femtosecond optical parametric oscillators with excitation
Output idler energies over the microjoule amount are attained with greatest conversion performance of eleven% for your amplifier stage, which can be greater than two situations better than the outcomes attained using an analogous sample of the commonly distribute substance AgGaS two .
Other than the compactness and benign operating characteristics, it absolutely was the large adaptability in design and style and output properties that led for the results of solid-state lasers over the past 40 yrs.
By employing intracavity dispersion Regulate, around-transform-constrained sign pulses of �?one hundred fs period with smooth single-peak spectrum are accomplished at 1264 nm, akin to an idler wavelength at 6440 nm. To the best of our knowledge, This can be the first time these functional idler powers during the deep-IR have already been created from the dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition price.
We report new experimental results around the section-matching Homes of yellow coloration HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers during the 0.944-10.5910 μm selection. In addition, we current new Sellmeier equations that provide a great copy of your current experimental benefits in addition to the posted facts factors for 2nd-harmonic technology of CO2 laser radiation at 9.
The calculated Main stage binding energies are compared with those of HgS, Fuel, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being unbiased on the technological disorders of crystal expansion. In distinction to the valence band spectrum, the distribution of electron states inside the bandgap of read more HgGa2S4 crystals is located to generally be strongly dependent on the technological situations of crystal advancement as shown through the photoluminescence Assessment.
Two parametric four-wave-mixing (FWM) procedures in Rb atoms are analyzed utilizing perturbation principle under the situation of rotating wave approximation. The two parametric FWM procedures are coupled when they're excited coherently by a brief laser pulse with a bandwidth encompassing the two corresponding higher Electrical power levels in the two FWM processes.
A way is produced to resolve the method of shortened equations describing parametric generation within a a person-frequency OPO cavity below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals as well as the exceptional reflection coefficient in the output mirror are estimated as opposed to the pump Electricity density Wp at distinctive values from the OPO nonstationarity .

Straightforward system for decreasing the depolarization loss ensuing from thermally induced birefringence in solid-point out lasers
12 μm and describe all frequency conversion strategies understood to date with them along with future probable purposes. Keyword phrases: Ternary and quaternary semiconductors, defect chalcopyrites, stable solutions, nonlinear optical crystals, mid-infrared
On this paper we theoretically investigate the most productive pump temporal shape for pulsed operation of optical parametric oscillators (OPOs). The theoretical Examination is made of solving the ideal control challenge utilizing the amount equation formalism. The OPO ideal buildup behavior is derived for virtually any OPO configuration, and we display which the best pump pulse condition is a double rectangle. The main rectangle is optimized for that buildup approach, when the next one is optimized for your continuous point out, and equally rely in a different way over the OPO mirror reflectivities plus the obtainable pump Strength and maximum peak electricity.
