053 μm. The absorption spectrum of ammonia was introduced to exhibit the feasibility in the made optical parametric oscillator system for spectroscopic measurements and gas detection.
We report over a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) dependant on the Kerr-lens-manner-locked Ti:sapphire laser because the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by the nonlinear crystal, CdSiP two , synchronously pumped inside to your MgO:PPLN femtosecond OPO, We have now created broadly tunable radiation across 5958�?117 nm applying immediate static cavity delay tuning, by using a most electricity of sixty four μW at 6791 nm, constrained with the absorption in mirror substrates together with polarization-dependent intracavity losses.
This technique lets the operation of extensively tunable optical parametric oscillators2 (OPO) and subsequent difference frequency generators3 making tunable pulses of high peak electricity. The higher Electrical power of the pump pulse trains has sure Advantages with the operation of the synchronously pumped OPO, e.g., comfortable balance demands, along with the prospective to work with massive cavity losses (e.g. metal mirrors) permitting huge tuning ranges with one set of mirrors and high output-coupling variables for pulse shortening.
.. [Exhibit whole summary] third-harmonic generation and parametric amplification with low-frequency pumping in periodically poled active nonlinear crystals may also be investigated. The Evaluation is completed for the case of a periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of making use of periodically poled active nonlinear crystals in laser gadgets with self-frequency conversion are talked about.
A laser gas analyzer is designed for deciding the composition of exhaled air by means of photoacoustic spectroscopy. The analyzer, determined by a broadband optical parametric oscillator and photoacoustic detector, presents large-precision immediate Evaluation in the multicomponent composition of human exhaled air for dynamic estimation in the performance of dealing with bronchus and lung health conditions.
The measured core stage binding energies are in contrast with These of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being unbiased over the technological conditions of crystal expansion. In distinction for the valence band spectrum, the distribution of electron states while in the bandgap of HgGa2S4 crystals is uncovered to become strongly dependent upon the technological ailments of crystal advancement as demonstrated with the photoluminescence Evaluation.
Optical Homes of orange phased HgGa2S4 crystal is investigated. Technology of tunable Center infrared radiation by second harmonic of tunable CO2 laser radiation has actually been shown. Second harmonic conversion effectiveness with respect to other infrared crystal has also been talked about.
A way is designed to solve the method of shortened equations describing parametric generation inside a just one-frequency OPO cavity under nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe two, and HgGa2S4 crystals as well as optimal reflection coefficient of the output mirror are approximated compared to the pump Power density Wp at different values from the OPO nonstationarity .

In this paper we theoretically examine by far the most successful pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Investigation contains solving the optimal Regulate difficulty utilizing the rate equation formalism. The OPO ideal buildup behavior is derived for almost any OPO configuration, and we present which the optimal pump pulse condition is actually a double rectangle. get more info The very first rectangle is optimized for your buildup process, whilst the next 1 is optimized with the regular condition, and both equally count in different ways on the OPO mirror reflectivities plus the offered pump Electricity and most peak energy.
Tunable mid-IR radiation is received through second harmonic technology of tunable CO2-laser radiation employing a CdGeAs2 crystal. Its angular tuning features with the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
