With the advent of latest nonlinear resources and single-frequency pump resources, There exists renewed interest in optical parametric oscillators (OPOs). One-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly both of those amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Output idler energies over the microjoule stage are attained with utmost conversion efficiency of eleven% for that amplifier phase, that's greater than two periods a lot better than the final results attained with the analogous sample of your extensively distribute substance AgGaS 2 .

In the two the instances received device mobile parameters are same, which shows the accuracy of current solution. The electronic band structures present the semiconducting habits in both of those the cases. The density of states plot may also be researched and talked about.
We report new experimental effects on the period-matching Qualities of yellow coloration HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers from the 0.944-ten.5910 μm selection. Additionally, we current new Sellmeier equations that supply a great replica of your current experimental success as well as the printed info details for 2nd-harmonic technology of CO2 laser radiation at nine.
The measured Main stage binding energies are in contrast with Those people of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves being independent within the technological circumstances of crystal growth. In contrast towards the valence band spectrum, the distribution of electron states inside the bandgap of HgGa2S4 crystals is identified to become strongly dependent upon the technological circumstances of crystal advancement as shown via the photoluminescence Examination.
The temperature dependence of refractive indices of optical products is characterized With this work by what we contact their normalized thermo-optic coefficients. They're identified experimentally by means of interferometric measurements of thermal growth and of changes in optical thickness at some laser wavelengths as function of temperature. An appropriate vectorial formalism applied to these knowledge makes check here it possible for predicting the thermal evolution with the refractive index all around the valuable variety of transparency.

Vibrational spectra of Li-made up of nonlinear crystals as well as their software in THz radiation era are reviewed. Applying an illustration of LiGaS2, the defect effect on spectroscopic attributes is proven. Large-temperature annealing in a proper atmosphere allows a person to remove extended and stage defects and to Increase the transparency. Electrical power composition and parameters of key place defects for instance anion vacancy (File-Middle) and cation antisite defect GaLi calculated from the 1st rules concur properly with the experimental results.
The technology of growing mercury thiogallate crystals (HgGa2S4) is enhanced and superior-quality bulk samples are produced. The essential optical and thermal Houses of those crystals are studied. The transmission spectra of mercury thiogallate are measured and its nonlinear characteristics such as the quadratic susceptibility, tuning curves, and the optical-damage resistance are also identified.
Interference is observed in between the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
for your detection of molecular trace gasses. The oscillation threshold, output power and steadiness of The only resonant
A pulsed TEA CO2 laser was utilised to research the effect of pump radiation parameters (method construction, wavelength, and pulse period), focusing conditions, absorption coefficient, and temperature to the efficiency of conversion into the 2nd harmonic and on angular dependences of phase matching in ZnGeP2 crystals. Fantastic agreement betweeen experimental and theoretical effects is observed. Read through much more
Distinction frequency mixing of strongly targeted Gaussian beams in periodically poled LiNbO3 was investigated. The beams had been centered inside the crystal with no destruction. Mixing of cw and pulsed laser programs was utilized to reduce the thermal lensing outcomes within this crystal. A reduced-electricity cw one.064‐μm Nd:YAG laser beam was applied given that the pump, Whilst the sign beam arrived from a picosecond optical .
