Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency generation in OPGaAs
The significance from the attained final results lies in The reality that to have the identical conversion in SHG or DFM, 1 now demands essential enter radiation with Significantly decreased intensity.

An easy system for cutting down the reduction that is because of depolarization ensuing from thermally induced anxiety birefringence in stable-condition lasers is documented. The procedure makes use of only one intracavity quarter-wave plate with its quick or slow axis aligned parallel to the popular airplane of polarization, defined by an intracavity polarizer.
A laser gasoline analyzer has been created for analyzing the composition of exhaled air via photoacoustic spectroscopy. The analyzer, according to a broadband optical parametric oscillator and photoacoustic detector, presents substantial-precision swift Investigation from the multicomponent composition of human exhaled air for dynamic estimation on the effectiveness of treating bronchus and lung diseases.
PA Ref-cell, which drastically decreases themeasurement errors of the methane concentration in thecase of instability
The temperature dependence of refractive indices of optical supplies is characterised In this particular function by what we contact their normalized thermo-optic coefficients. They are decided experimentally as a result of interferometric measurements of thermal growth and of variations in optical thickness at a handful of laser wavelengths as function of temperature. An acceptable vectorial formalism placed on these details makes it possible for predicting the thermal evolution on the refractive index all over the helpful range of transparency.
Based on the theories of phase matching and satisfactory composition ratio, the influence of composition ratio within the frequency conversions of two varieties (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In thought of corresponding sellmeier equations, period matching diagrams of 2nd harmonic era and optical parametric oscillations pumped by the favored Nd3+:YAG and Ho3+:YLF lasers were being calculated, in addition to appropriate composition ratios with many compositions.
Bigger-buy nonlinear processes in alternative products will also be thought of and also a discussion on substance suitability for down-conversion of in close proximity to-IR lasers in to the mid-IR to fulfill different software needs is also offered.
The technological know-how of increasing mercury click here thiogallate crystals (HgGa2S4) is enhanced and large-top quality bulk samples are manufactured. The basic optical and thermal Qualities of these crystals are examined. The transmission spectra of mercury thiogallate are measured and its nonlinear properties like the quadratic susceptibility, tuning curves, and the optical-problems resistance are determined.
Simple technique for decreasing the depolarization loss ensuing from thermally induced birefringence in strong-condition lasers
Notice: Author names will likely be searched from the key phrases area, also, but that may find papers wherever the person is outlined, as an alternative to papers they authored.
A pulsed TEA CO2 laser was employed to research the impact of pump radiation parameters (mode structure, wavelength, and pulse period), concentrating disorders, absorption coefficient, and temperature over the performance of conversion into the next harmonic and on angular dependences of stage matching in ZnGeP2 crystals. Great agreement betweeen experimental and theoretical results is noticed. Read through extra
Diode-pumped optical parametric oscillation continues to be shown for The very first time to our know-how in a single 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 create 1084-nm laser oscillation.
