.. [Show whole abstract] parametric oscillator. The 2 independently focused beams ended up made to overlap inside the crystal. The focusing parameters of the two beams had been about the identical. The concentrating perform formulated by Boyd and Kleinman for tightly concentrated beams was extended to periodically poled crystals so that you can fit the temperature-tuning curve. A 0.sixty six%/W performance was obtained for the real difference frequency mixing process.
A method-locked tunable dye laser has been created and that is synchronously pumped at high repetition charges with the doubled output of the method-locked Nd:YAG laser. The dye laser supplies powerful pulses of 35 psec length that happen to be extensively tunable, of close to-remodel-limited bandwidth, As well as in time coincidence Using the pumping pulses.
The primary-ideas density useful calculations are carried out to check the geometries and electronic constructions of HgGa2X4 (X = S, Se, Te) semiconductors with defect chalcopyrite constructions, plus the optical Houses of all crystals are investigated systematically. The effects point out that these compounds have related band buildings and the band hole decreases from S to Se to Te. To the linear optical Qualities, three crystals show good gentle transmission from the IR and aspect noticeable locations, and specifically, HgGa2S4 and HgGa2Se4 crystals possess average birefringence.
.. [Present whole summary] 3rd-harmonic generation and parametric amplification with small-frequency pumping in periodically poled Energetic nonlinear crystals may also be investigated. The Examination is performed for the case of the periodically poled Nd:Mg:LiNbO3 crystal. Views of applying periodically poled active nonlinear crystals in laser equipment with self-frequency conversion are discussed.
Self-referenced octave-large subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
triggered oscillations during the idler wavelength of under 200MHz about 300s; the brief-phrase security was fewer than 3MHz
The era of tunable pico- and femtosecond light pulses with parametric frequency conversion procedures has captivated improved focus recently1. New crystal materials, as BBO, LBO, and KTP, with remarkable nonlinearity and high injury threshold are actually out there, and pump lasers of improved stability allow the dependable Procedure of optical parametric oscillators. Parametric devices pumped ... [Display whole summary] either by cw modelocked lasers or by single intensive ultrashort pulses are actually created. With this contribution parametric systems are discussed which might be pumped by rigorous pulse trains of some microseconds period and repetition fees up to 50Hz.
This re-creation has become read more updated and revised to includeimportant developments, principles and technologies that haveemerged Because the publication of the first version.
Additionally, we performed a numerical simulation of chirped-pulse OPOs (CPOPOs) and revealed the spectral profile from the output from the CPOPO was pertinent to each the parametric get profile in the nonlinear crystal and also the intra-cavity significant-purchase dispersion.
Topics could be refined further more while in the search engine results. The Topic aspect will reveal the higher-level subject areas associated with the articles or blog posts returned within the search results. Specific COLLECTIONS
... The 1st info to the refractive index of orange HGS printed by Levine et al. [35] included only several wavelengths within the obvious and close to-IR equally as an indication of the feasibility of this crystal for birefringent period-matching. The refractive indices with the orange phase had been measured and tabulated amongst 0.
for that detection of molecular trace gasses. The oscillation threshold, output ability and steadiness of The one resonant
In this paper we theoretically look into quite possibly the most productive pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Evaluation is made up of resolving the optimum Command challenge utilizing the amount equation formalism. The OPO exceptional buildup conduct is derived for virtually any OPO configuration, and we present the optimum pump pulse form is usually a double rectangle. The very first rectangle is optimized to the buildup approach, whilst the next just one is optimized with the steady state, and each depend in different ways to the OPO mirror reflectivities as well as the accessible pump Strength and most peak ability.
Tunable mid-IR radiation is attained during next harmonic era of tunable CO2-laser radiation using a CdGeAs2 crystal. Its angular tuning characteristics within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
