Optical parametric oscillator pumped at ~one µm with intracavity mid-IR big difference-frequency technology in OPGaAs
We report over a femtosecond optical parametric oscillator (OPO) for your deep-infrared (deep-IR) depending on the Kerr-lens-method-locked Ti:sapphire laser because the pump supply. By deploying a novel cascaded intracavity arrangement, comprising a femtosecond OPO determined by 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 working with quick static cavity hold off tuning, with a optimum electrical power of 64 μW at 6791 nm, limited by the absorption in mirror substrates as well as polarization-dependent intracavity losses.
Apart from the compactness and benign functioning options, it absolutely was the large overall flexibility in layout and output qualities that led towards the achievements of sound-condition lasers throughout the last forty a long time.
A straightforward procedure for minimizing the loss that is due to depolarization resulting from thermally induced anxiety birefringence in reliable-condition lasers is reported. The procedure employs an individual intracavity quarter-wave plate with its fast or sluggish axis aligned parallel to the popular plane of polarization, described by an intracavity polarizer.
OPO were enhanced by optimizing pump beam waistline and OPO cavity duration. The two air-spaced and strong etalons ended up analyzed to frequency
PA Ref-cell, which drastically minimizes themeasurement glitches of your methane focus in thecase of instability
The temperature dependence of refractive indices of optical products is characterised With this function by what we simply call their normalized thermo-optic coefficients. They are identified experimentally by means of interferometric measurements of thermal enlargement and of variations in optical thickness at several laser wavelengths as function of temperature. An appropriate vectorial formalism placed on these info allows predicting the thermal evolution from the refractive index everywhere in the beneficial variety of transparency.
Pumping mid-IR optical parametric oscillators in close proximity to one μm is interesting for its simplicity and electricity scaling capability. To this aim, extensive bandgap non-oxide nonlinear crystals are essential.
Bigger-get nonlinear processes in substitute check here products also are deemed as well as a dialogue on content suitability for down-conversion of around-IR lasers into your mid-IR to fulfill different application prerequisites is also presented.
Topics can be refined further more inside the search results. The subject side will expose the superior-amount topics connected to the content articles returned while in the search results. Specific COLLECTIONS
