Optical parametric oscillator pumped at ~one µm with intracavity mid-IR difference-frequency era in OPGaAs
A manner-locked tunable dye laser has become created which is synchronously pumped at significant repetition costs by the doubled output of the mode-locked Nd:YAG laser. The dye laser provides powerful pulses of 35 psec length which are greatly tunable, of around-completely transform-limited bandwidth, As well as in time coincidence With all the pumping pulses.
This technique permits the Procedure of broadly tunable optical parametric oscillators2 (OPO) and subsequent big difference frequency generators3 producing tunable pulses of significant peak electrical power. The upper Vitality of your pump pulse trains has specific Gains for that Procedure of a synchronously pumped OPO, e.g., peaceful balance prerequisites, as well as the probable to operate with big cavity losses (e.g. steel mirrors) letting large tuning ranges with just one list of mirrors and significant output-coupling factors for pulse shortening.
A simple method for decreasing the loss that is because of depolarization resulting from thermally induced stress birefringence in solid-point out lasers is documented. The method uses only one intracavity quarter-wave plate with its speedy or sluggish axis aligned parallel to the popular airplane of polarization, outlined by an intracavity click here polarizer.
A laser gasoline analyzer has actually been designed for deciding the composition of exhaled air by means of photoacoustic spectroscopy. The analyzer, depending on a broadband optical parametric oscillator and photoacoustic detector, presents large-precision immediate Evaluation with the multicomponent composition of human exhaled air for dynamic estimation on the effectiveness of managing bronchus and lung conditions.
The high conversion effectiveness and wide selection of radiation wavelength tuning lets to hope that this materials could contend with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals Despite the sizeable difficulty of big dimension crystals expansion system.
Taxonomy, chemical bonding relations and nonlinear optical properties of noncentrosymmetric sulfide crystals
Determined by the theories of phase matching and suitable composition ratio, the affect of composition ratio over the frequency conversions of two types (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, period matching diagrams of 2nd harmonic technology and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers were calculated, and also suitable composition ratios with a variety of compositions.
