053 μm. The absorption spectrum of ammonia was offered to display the feasibility on the made optical parametric oscillator method for spectroscopic measurements and fuel detection.
Results of thermal conductivity measurements are reported for several of the greater not long ago produced nonlinear optical crystals. New or substantially revised values of thermal conductivity were received in six components. Noteworthy thermal conductivities measured were These for AgGaS2 [0.014 W/(cm K) and 0.
crystals with ultrafast Yb-ion laser pump is proposed. The final results sort a helpful reference for the choice of supplies
The principle of chemical transport reactions (volatilization of a material through a lower-volatile chemical intermediate in a temperature T1 and again-reaction in the mixture in a temperature T2, using the temperature dependence with the chemical equilibrium included) can be a beneficial Software for escalating solitary crystals of many products which can not be conveniently acquired in the melt.
A laser fuel analyzer is suitable for identifying the composition of exhaled air via photoacoustic spectroscopy. The analyzer, based on a broadband optical parametric oscillator and photoacoustic detector, gives superior-precision speedy analysis in the multicomponent composition of human exhaled air for dynamic estimation of the performance of treating bronchus and lung ailments.
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Including signal and idler, it could be repeatedly tuned from one.261 as a result of two.532 μm by varying the pump wavelength. Two main enhancements ended up obtained, such as the relationship of your sign and idler tuning ranges plus the large output pulse Strength from the signal and idler tuning ... [Exhibit complete abstract] ranges. The initial enhancement was accomplished by getting two specific sets of phase-matching angles. The next enhancement was understood by utilizing 5 sets of resonator mirrors for oscillating both signal or idler.
Taxonomy, chemical bonding relations and nonlinear optical properties of noncentrosymmetric sulfide crystals
A method is developed to unravel the procedure of shortened equations describing parametric generation inside of a 1-frequency OPO cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals along with the exceptional reflection coefficient from the output mirror are approximated vs . the pump Power density Wp at unique values of the OPO nonstationarity .
Furthermore, we done a numerical simulation of chirped-pulse OPOs (CPOPOs) and discovered which the spectral profile with the output from a CPOPO was pertinent to the two the parametric obtain profile from the nonlinear crystal and also the intra-cavity significant-get dispersion.
Topics could be refined even further in the search results. The Topic aspect will reveal the significant-amount subject areas related to the articles or blog posts returned from the search engine results. Distinctive COLLECTIONS
Uncomplicated process more info for reducing the depolarization decline ensuing from thermally induced birefringence in sound-condition lasers
The noticed f -to- 2 file frequency beats, originating directly from the OPO, may be used for self-referencing and period locking of the pump laser comb without having for supercontinuum era. With a mean output electricity of �?30 mW , this setup might be valuable for many different spectroscopic programs from the mid-IR.
A simple quantum product agrees very well Along with the experimental effects and causes it to be achievable to interpret the effect in terms of
Tunable mid-IR radiation is received throughout second harmonic era of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning properties in the CO2- laser wavelength, angular acceptance angle and spectral acceptance are calculated.
