Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR distinction-frequency technology in OPGaAs
We report with a femtosecond optical parametric oscillator (OPO) with the deep-infrared (deep-IR) depending on the Kerr-lens-manner-locked Ti:sapphire laser as being the pump resource. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO based on the nonlinear crystal, CdSiP 2 , synchronously pumped inner to the MgO:PPLN femtosecond OPO, Now we have produced broadly tunable radiation throughout 5958�?117 nm using swift static cavity delay tuning, by using a utmost electricity of 64 μW at 6791 nm, confined via the absorption in mirror substrates as well as polarization-dependent intracavity losses.

.. [Demonstrate total summary] third-harmonic generation and parametric amplification with very low-frequency pumping in periodically poled Energetic nonlinear crystals may also be investigated. The Evaluation is performed for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Perspectives of employing periodically poled active nonlinear crystals in laser equipment with self-frequency conversion are discussed.
OPO have been improved by optimizing pump beam waistline and OPO cavity size. Equally air-spaced and good etalons had been examined to frequency
PA Ref-mobile, which appreciably lessens themeasurement mistakes of the methane concentration in thecase of instability
The temperature dependence of refractive indices of optical supplies is characterised Within this function by what we connect with 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 perform of temperature. An acceptable vectorial formalism applied to these facts will allow predicting the thermal evolution in the refractive index everywhere in the helpful array of transparency.

Better-buy nonlinear processes in option supplies will also be viewed as along with a discussion on material suitability for down-conversion of in close proximity to-IR lasers into your mid-IR to fulfill several software needs is likewise introduced.
Analysis of latest, promising large-band-gap nonlinear crystals to the mid-IR is given. We focused on ternary and quaternary chalcogenides and centered on their own Bodily and chemical Houses, which in addition to linear and nonlinear optical Houses, decide check here the effectiveness of crystal utilization in particular laser experiments. The correlation among the composition, structure and output parameters together with the trends in improvements of the key features for instance band hole, nonlinear susceptibility, laser hurt threshold, and many others, are shown.
Interference is observed involving the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic

One-step sub-200 fs mid-infrared technology from an optical parametric oscillator synchronously pumped by an erbium fiber laser
Diode-pumped optical parametric oscillation has become demonstrated for The very first time to our understanding in one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take in the 812-nm radiation to make 1084-nm laser oscillation.
