and operating ailments for the practical style and design of high energy femtosecond optical parametric oscillators with excitation
The significance in the received final results lies in The reality that to get the same conversion in SHG or DFM, one particular now needs essential enter radiation with A lot lessen depth.
crystals with ultrafast Yb-ion laser pump is proposed. The results variety a useful reference for the choice of resources
By employing intracavity dispersion control, close to-renovate-minimal signal pulses of �?100 fs duration with easy solitary-peak spectrum are realized at 1264 nm, corresponding to an idler wavelength at 6440 nm. To the ideal of our awareness, This can be The very first time such sensible idler powers inside the deep-IR are already generated from the dispersion-compensated CSP femtosecond OPO at sub-one hundred MHz repetition price.
OPO were improved by optimizing pump beam waistline and OPO cavity size. Both of those air-spaced and strong etalons ended up examined to frequency
Within this Introduction we will provide a short overview of your essential milestones in the event of sound-point out lasers, explore the array of effectiveness parameters achievable with these lasers, and point out main programs.
The temperature dependence of refractive indices of optical resources is characterized During this operate by what we phone their normalized thermo-optic coefficients. These are definitely determined experimentally via interferometric measurements of thermal enlargement and of adjustments in optical thickness at a few laser wavelengths as functionality of temperature. A suitable vectorial formalism applied to these data makes it possible for predicting the thermal evolution in the refractive index everywhere in the practical variety of transparency.
According to the theories of section matching and suitable composition ratio, the affect of composition ratio over the frequency conversions of two sorts (phases) of Cd doped Hg1-xCdxGa2S4 was investigated. In consideration click here of corresponding sellmeier equations, stage matching diagrams of next harmonic technology and optical parametric oscillations pumped by the popular Nd3+:YAG and Ho3+:YLF lasers were being calculated, as well as suitable composition ratios with many compositions.

stabilize and tune the OPO, from which the reliable etalon gave a far better performance. Temperature oscillations within the PPLN crystal
... The 1st knowledge within the refractive index of orange HGS printed by Levine et al. [35] bundled only several wavelengths within the obvious and near-IR equally as a demonstration from the feasibility of the crystal for birefringent section-matching. The refractive indices for your orange period ended up calculated and tabulated involving 0.
12 μm and describe all frequency conversion strategies realized so far with them and also long term potential apps. Key terms: Ternary and quaternary semiconductors, defect chalcopyrites, solid remedies, nonlinear optical crystals, mid-infrared
Single-phase sub-200 fs mid-infrared era from an optical parametric oscillator synchronously pumped by an erbium fiber laser
three% rms more than 12 h in excellent beam high quality. The around-IR sign pulses through the OPO Use a Gaussian pulse length of �?19 ps , calculated at 1284 nm. We have now investigated the temperature tuning qualities of your OPO and compared the data While using the theoretical calculations making use of the most recent Sellmeier equations and thermo-optic coefficients with the crystal. To the top of our expertise, Here is the very first picosecond OPO dependant on CSP working at MHz repetition rates.
