Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR difference-frequency technology in OPGaAs
We report on a femtosecond optical parametric oscillator (OPO) to the deep-infrared (deep-IR) according to the Kerr-lens-manner-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO depending on the nonlinear crystal, CdSiP 2 , synchronously pumped inside into a MgO:PPLN femtosecond OPO, Now we have created broadly tunable radiation throughout 5958�?117 nm employing swift static cavity delay tuning, which has a greatest electricity of 64 μW at 6791 nm, minimal through the absorption in mirror substrates in addition to polarization-dependent intracavity losses.
Besides the compactness and benign running functions, it absolutely was the enormous versatility in structure and output attributes that led on the results of solid-condition lasers during the last 40 a long time.
.. [Exhibit full abstract] 3rd-harmonic technology and parametric amplification with low-frequency pumping in periodically poled Lively nonlinear crystals will also be investigated. The Examination is performed for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of employing periodically poled Lively nonlinear crystals in laser products with self-frequency conversion are discussed.
A laser gas analyzer has become designed for identifying the composition of exhaled air by means of photoacoustic spectroscopy. The analyzer, based upon a broadband optical parametric oscillator and photoacoustic detector, provides significant-precision immediate Examination of your multicomponent composition of human exhaled air for dynamic estimation with the efficiency of treating bronchus and lung conditions.
We report the implementation of the KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Like signal and idler, it could be continuously tuned from one.261 by way of two.532 μm by different the pump wavelength. Two key improvements had been obtained, such as the relationship in the sign and idler tuning ranges and the higher output pulse Strength throughout the sign and idler tuning ... [Demonstrate entire summary] ranges. The initial improvement was accomplished by exploring two individual sets of section-matching angles. The 2nd advancement was understood by making use of five sets of resonator mirrors for oscillating both signal or idler.
The generation of tunable pico- and femtosecond mild pulses with parametric frequency conversion processes has captivated increased consideration recently1. New crystal products, as BBO, LBO, and KTP, with exceptional nonlinearity and higher injury threshold are now offered, and pump lasers of enhanced steadiness enable the dependable Procedure of optical parametric oscillators. Parametric equipment pumped ... [Display full abstract] either by cw modelocked lasers or by one intensive ultrashort pulses are created. During this contribution parametric programs are discussed which are pumped by rigorous pulse trains of some microseconds duration and repetition rates around 50Hz.
air hole and psyched in collection by a typical click here pump beam. The period in the interference is dependent upon the stage shifts at three frequencies.
Modeling and experimental analyze on phase matching of 2nd harmonic technology in numerous colour Hg Ga two S four crystals are performed. Utilizing the regarded Sellmeier equations, the dispersion relation with weighting proportionally to small-wavelength boundary in the crystal transparency band is proposed.
stabilize and tune the OPO, from which the strong etalon gave a greater effectiveness. Temperature oscillations from the PPLN crystal
Normalization from the absorption alerts inside the PAD is performed in accordance with the absorption indicators from the fuel-loaded
Notice: Writer names might be searched in the key phrases discipline, also, but that could locate papers the place the person is pointed out, instead of papers they authored.
The selected nonlinear crystals exhibit bigger nonlinear conversion efficiency when compared to AgGaS two , with BaGa two GeS six In addition supplying a narrower angular spectrum of spontaneous parametric down conversion, beneficial in interferometric strategies. Our results create a pathway for integrating Highly developed crystal technologies into mid-infrared metrology and imaging methods, environment the stage for long run developments in nonlinear interferometry and spectroscopy.
3% rms about 12 h in superior beam high-quality. The close to-IR sign pulses from your OPO have a Gaussian pulse length of �?19 ps , calculated at 1284 nm. We've got investigated the temperature tuning qualities with the OPO and in comparison the information With all the theoretical calculations working with The latest Sellmeier equations and thermo-optic coefficients for that crystal. To the most effective of our know-how, This can be the first picosecond OPO determined by CSP functioning at MHz repetition rates.
