and functioning problems for the practical style and design of higher ability femtosecond optical parametric oscillators with excitation
We report with a femtosecond optical parametric oscillator (OPO) for the deep-infrared (deep-IR) based upon the Kerr-lens-manner-locked Ti:sapphire laser as the pump source. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO according to the nonlinear crystal, CdSiP two , synchronously pumped inside to your MgO:PPLN femtosecond OPO, We've got created broadly tunable radiation across 5958�?117 nm making use of swift static cavity delay tuning, by using a most electricity of 64 μW at 6791 nm, constrained from the absorption in mirror substrates and polarization-dependent intracavity losses.

A simple technique for lessening the loss that is due to depolarization resulting from thermally induced strain birefringence in solid-state lasers is noted. The approach uses just one intracavity quarter-wave plate with its rapidly or sluggish axis aligned parallel to the preferred plane of polarization, described by an intracavity polarizer.
We report new experimental effects around the period-matching properties of yellow shade HgGa2S4 crystals for harmonic technology of the Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-10.5910 μm array. In addition, we present new Sellmeier equations that offer a fantastic reproduction of the current experimental effects along with the revealed data points for next-harmonic technology of CO2 laser radiation at 9.
PA Ref-mobile, which noticeably decreases themeasurement faults from the methane concentration in thecase of instability
The temperature dependence of refractive indices of optical materials is characterized On this do the job by what we call their normalized thermo-optic coefficients. They're established experimentally via interferometric measurements of thermal expansion and of improvements in optical thickness at a number of laser wavelengths as function of temperature. An appropriate vectorial formalism placed on these information will allow predicting the thermal evolution in the refractive index everywhere in the helpful selection of transparency.
Depending on the theories of stage matching and acceptable composition ratio, the influence of composition ratio around the frequency conversions of two forms (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration of corresponding sellmeier equations, period matching diagrams of 2nd harmonic technology and optical parametric oscillations pumped by more info the popular Nd3+:YAG and Ho3+:YLF lasers have been calculated, along with acceptable composition ratios with various compositions.
Vibrational spectra of Li-containing nonlinear crystals and their application in THz radiation generation are discussed. Utilizing an example of LiGaS2, the defect impact on spectroscopic properties is revealed. Significant-temperature annealing in a suitable atmosphere allows one to eliminate prolonged and place defects and also to Enhance the transparency. Vitality structure and parameters of key position defects including anion vacancy (File-Middle) and cation antisite defect GaLi calculated from the very first ideas agree very well With all the experimental outcomes.
The 3rd harmonic of CO2-laser radiation continues to be received by passing the laser beam by way of two CdGeAs2 crystals in tandem, with the 1st crystal oriented for next-harmonic generation and the second for sum mixing. Utilizing This method, We have now obtained a mean external conversion performance of one.
Straightforward technique for decreasing the depolarization reduction ensuing from thermally induced birefringence in strong-state lasers
for the detection of molecular trace gasses. The oscillation threshold, output ability and balance of The only resonant
A pulsed TEA CO2 laser was employed to analyze the influence of pump radiation parameters (mode framework, wavelength, and pulse duration), concentrating situations, absorption coefficient, and temperature on the effectiveness of conversion into the 2nd harmonic and on angular dependences of stage matching in ZnGeP2 crystals. Superior arrangement betweeen experimental and theoretical success is observed. Browse extra
This is the initial illustration of a broadband OPO working across the molecular fingerprint location, and we demonstrate its potential by conducting broadband Fourier-rework spectroscopy making use of h2o vapor plus a polystyrene reference conventional.
