053 μm. The absorption spectrum of ammonia was presented to show the feasibility from the made optical parametric oscillator program for spectroscopic measurements and gas detection.
A mode-locked tunable dye laser has been created that's synchronously pumped at high repetition rates from the doubled output of the manner-locked Nd:YAG laser. The dye laser presents powerful pulses of 35 psec duration that are broadly tunable, of close to-change-minimal bandwidth, and in time coincidence with the pumping pulses.

Experiments of practical pump laser systems appropriate for ultrafast femtosecond OPOs based upon CdSiP 2 are reviewed, as well as favorable linear and nonlinear optical Qualities, as well as special stage-matching characteristics of CdSiP 2 , are offered utilizing The latest Sellmeier equations for the material. The explained experimental final results depict the best output pulse Strength and history average power in the ultrafast picosecond and femtosecond time scales over the 6–7 μm spectral range to date.
A laser fuel analyzer has long been made for identifying the composition of exhaled air through photoacoustic spectroscopy. The analyzer, determined by a broadband optical parametric oscillator and photoacoustic detector, supplies superior-precision rapid Investigation of the multicomponent composition of human exhaled air for dynamic estimation from the effectiveness of managing bronchus and lung illnesses.
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Like signal and idler, it may be repeatedly tuned from 1.261 by 2.532 μm by various the pump wavelength. Two major enhancements ended up attained, including the link on the signal and idler tuning ranges plus the higher output pulse Vitality from the sign and idler tuning ... [Show full summary] ranges. The first advancement was realized by exploring two individual sets of section-matching angles. The next advancement was understood by making use of 5 sets of resonator mirrors for oscillating either signal or idler.

air gap and energized in collection by a common pump beam. The stage with the interference depends on the section shifts at 3 frequencies.
The precise warmth and thermal conductivity of HgGa2S4 are calculated. It is actually concluded more info which the blended Qualities of HgGa2S4 crystals can provide for them a number one placement One of the products Employed in nonlinear-optical products for mid-IR-frequency conversion.
This paper reviews the modern developments in crystal progress and singly resonant optical parametric oscillators for that technology of higher solitary pulse Power and ordinary powers in the mid-IR from three to 10 μm.
Interference is noticed between the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser system. By utilizing a three hundred μm lengthy magnesium-doped periodically poled LiNbO three crystal as the parametric acquire medium and configuring the OPO to be a chirped-pulse oscillator, we acquired mid-infrared emission having an instantaneous bandwidth covering 3084�?466 nm. This final result represents, to the top of our know-how, the widest instantaneous bandwidth received from a Yb-fiber-laser-pumped singly resonant OPO, demonstrating the enormous potential of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-rapidly OPOs.
On this paper we theoretically look into one of the most successful pump temporal condition for pulsed operation of optical parametric oscillators (OPOs). The theoretical Evaluation contains solving the optimum Handle problem utilizing the price equation formalism. The OPO ideal buildup conduct is derived for almost any OPO configuration, and we show that the exceptional pump pulse shape is actually a double rectangle. The initial rectangle is optimized for your buildup system, when the next a single is optimized with the constant state, and both depend in a different way on the OPO mirror reflectivities and also the readily available pump Strength and most peak electric power.
Tunable mid-IR radiation is obtained all through second harmonic technology of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning characteristics for the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
