Solid-Condition Laser Engineering is prepared from an industrialperspective and discusses intimately the characteristics, layout, design and sensible challenges of solid-statelasers. Emphasis is placed on engineering and practicalconsiderations, that has a phenomenological treatment usingmodelsbeing desired to abstract mathematical derivations.
Output idler energies to the microjoule stage are obtained with most conversion effectiveness of 11% with the amplifier phase, that is a lot more than two occasions much better than the effects received by having an analogous sample from the widely unfold content AgGaS two .

By utilizing intracavity dispersion Handle, near-change-confined sign pulses of �?a hundred fs period with smooth one-peak spectrum are realized at 1264 nm, comparable to an idler wavelength at 6440 nm. To the most beneficial of our know-how, this is The 1st time these useful idler powers inside the deep-IR are already generated from a dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition charge.
OPO ended up enhanced by optimizing pump beam waist and OPO cavity duration. Both air-spaced and sound etalons have been analyzed to frequency
We report the implementation of a KTP optical parametric oscillator pumped by a pulsed Ti:sapphire laser. Which includes sign and idler, it may be consistently tuned from 1.261 as a result of two.532 μm by varying the pump wavelength. Two significant enhancements ended up attained, such as the link from the signal and idler tuning ranges and also the substantial output pulse Vitality through the sign and idler tuning ... [Exhibit comprehensive summary] ranges. The first enhancement was achieved by identifying two individual sets of stage-matching angles. The second advancement was understood through the use of five sets of resonator mirrors for oscillating possibly sign or idler.
Taxonomy, chemical bonding relations and nonlinear optical properties of noncentrosymmetric sulfide crystals
A way is produced to resolve the system of shortened equations describing parametric era in the one-frequency OPO cavity underneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals as well as the exceptional reflection coefficient with the output mirror are estimated versus the pump Electrical power density Wp at various values of the OPO nonstationarity .
Vibrational spectra of Li-that contains nonlinear crystals as well as their application in THz radiation technology are mentioned. Applying an illustration of LiGaS2, the defect effect on spectroscopic attributes is revealed. Substantial-temperature annealing in a correct environment will allow just one to eliminate extended and place defects also to Enhance the transparency. Electricity structure and parameters of key stage defects for example anion vacancy (File-Middle) and cation antisite defect GaLi calculated from the very first principles agree well Along with the experimental final results.
The technological know-how of growing mercury thiogallate crystals (HgGa2S4) is improved and high-high-quality bulk samples are developed. The basic optical and thermal properties of those crystals are analyzed. The transmission spectra of mercury thiogallate are calculated and its get more info nonlinear features like the quadratic susceptibility, tuning curves, and the optical-hurt resistance also are decided.
... The initial facts on the refractive index of orange HGS printed by Levine et al. [35] involved only several wavelengths while in the obvious and close to-IR equally as an illustration of the feasibility of the crystal for birefringent period-matching. The refractive indices with the orange section were calculated and tabulated involving 0.
for your detection of molecular trace gasses. The oscillation threshold, output electricity and balance of The one resonant
A pulsed TEA CO2 laser was used to analyze the result of pump radiation parameters (mode structure, wavelength, and pulse period), focusing circumstances, absorption coefficient, and temperature on the performance of conversion into the second harmonic and on angular dependences of section matching in ZnGeP2 crystals. Superior arrangement betweeen experimental and theoretical benefits is observed. Go through extra
3% rms above twelve h in superior beam excellent. The around-IR signal pulses from your OPO Use a Gaussian pulse length of �?19 ps , calculated at 1284 nm. Now we have investigated the temperature tuning properties of your OPO and in contrast the data with the theoretical calculations making use of The newest Sellmeier equations and thermo-optic coefficients for the crystal. To the top of our know-how, this is the first picosecond OPO based on CSP working at MHz repetition premiums.
