053 μm. The absorption spectrum of ammonia was introduced to display the feasibility on the made optical parametric oscillator process for spectroscopic measurements and gas detection.
Results of thermal conductivity measurements are described for quite a few of the greater not long ago formulated nonlinear optical crystals. New or considerably revised values of thermal conductivity had been attained in six components. Noteworthy thermal conductivities calculated ended up Individuals for AgGaS2 [0.014 W/(cm K) and 0.
This system allows the Procedure of greatly tunable optical parametric oscillators2 (OPO) and subsequent variance frequency generators3 developing tunable pulses of large peak electricity. The upper Power of the pump pulse trains has selected Advantages for the operation of a synchronously pumped OPO, e.g., peaceful security requirements, plus the opportunity to operate with substantial cavity losses (e.g. steel mirrors) enabling huge tuning ranges with just one list of mirrors and higher output-coupling factors for pulse shortening.
.. [Exhibit full abstract] third-harmonic generation and parametric amplification with reduced-frequency pumping in periodically poled active nonlinear crystals are also investigated. The Investigation is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of making use of periodically poled active nonlinear crystals in laser equipment with self-frequency conversion are reviewed.
A laser fuel analyzer is suitable for identifying the composition of exhaled air by the use of photoacoustic spectroscopy. The analyzer, based on a broadband optical parametric oscillator and photoacoustic detector, supplies superior-precision speedy Investigation of the multicomponent composition of human exhaled air for dynamic estimation in the effectiveness of managing bronchus and lung disorders.
brought on oscillations in the idler wavelength of under 200MHz in excess of 300s; the limited-expression steadiness was fewer than 3MHz
Optical Qualities of orange phased HgGa2S4 crystal is investigated. Era of tunable Center infrared radiation by 2nd harmonic of tunable CO2 laser radiation has become demonstrated. Second harmonic conversion efficiency with regard to other infrared crystal has also been talked over.
A technique is produced to unravel the system of shortened equations describing parametric era inside a 1-frequency OPO cavity below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals as well as optimum reflection coefficient with the output mirror are approximated compared to the pump Strength density Wp at different values on the OPO nonstationarity .

... The 1st information about the refractive index of orange HGS posted by Levine et al. [35] incorporated only several wavelengths in the noticeable and in close proximity to-IR equally as a demonstration on the feasibility of the crystal for birefringent period-matching. The refractive indices for that orange period were being calculated and tabulated in between 0.
Quantum mechanical dependent initially theory calculations are used to acquire the unit cell lattice parameters of mercury thiogallate (HgGa2S4) in defect stannite composition for The very first time. For this, we handled HgGa2S4 in two different types of web-site symmetries in the exact same Room group.
On this paper we theoretically examine one of the most economical pump temporal shape for pulsed operation of optical parametric oscillators (OPOs). The theoretical analysis is made of fixing the ideal Management trouble utilizing the level equation formalism. The OPO best buildup conduct is derived for virtually any OPO configuration, and we clearly show that the optimum pump pulse shape is often a double rectangle. The initial rectangle is optimized for that buildup approach, even though the second one is optimized for that continuous state, and both of those depend get more info in another way about the OPO mirror reflectivities as well as the accessible pump Strength and highest peak ability.
Here is the initially illustration of a broadband OPO working through the molecular fingerprint location, and we demonstrate its potential by conducting broadband Fourier-remodel spectroscopy making use of drinking water vapor plus a polystyrene reference typical.
