and operating ailments for the practical design of high electricity femtosecond optical parametric oscillators with excitation
The significance of your obtained final results lies in the fact that to obtain the similar conversion in SHG or DFM, one particular now involves elementary input radiation with much lower depth.
Other than the compactness and benign functioning attributes, it absolutely was the large adaptability in design and style and output characteristics that led towards the good results of strong-state lasers throughout the last forty several years.
By implementing intracavity dispersion Management, in the vicinity of-completely transform-confined sign pulses of �?100 fs period with easy single-peak spectrum are achieved at 1264 nm, similar to an idler wavelength at 6440 nm. To the ideal of our know-how, This is often The 1st time these kinds of functional idler powers inside the deep-IR have already been generated from the dispersion-compensated CSP femtosecond OPO at sub-100 MHz repetition charge.
In this function, we present what's, to our expertise, the main measurements of the quantum period diffusion noise of a cw OPO. Read through a lot more
PA Ref-mobile, which considerably lowers themeasurement mistakes with the methane focus in thecase of instability
The temperature dependence of refractive indices of optical products is characterized During this operate by what we get in touch with their normalized thermo-optic coefficients. These are definitely established experimentally by way of interferometric measurements of thermal enlargement and of alterations in optical thickness at a handful of laser wavelengths as purpose of temperature. A suitable vectorial formalism applied to these info enables predicting the thermal evolution of the refractive index everywhere in the useful selection of transparency.
air gap and enthusiastic in collection by a typical pump beam. The section of your interference depends on the period shifts at three frequencies.
Sound condition polymerization of diacetylenes The crystal composition of HAlSi2O6 by using a keatite-form framework Syntheses and crystal buildings of α
stabilize and tune the OPO, from which the stable etalon gave a far better efficiency. Temperature oscillations in the PPLN crystal
... The primary info over the refractive index of orange HGS revealed by Levine et al. [35] bundled only number of wavelengths in the noticeable and in the vicinity of-IR just as an illustration with the feasibility of the crystal for birefringent phase-matching. The refractive indices to the orange period have been calculated and tabulated amongst 0.
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser process. By employing a three hundred μm long magnesium-doped periodically poled LiNbO 3 crystal since the parametric achieve medium and configuring the OPO for a chirped-pulse oscillator, we received mid-infrared emission owning an instantaneous bandwidth masking 3084�?466 nm. This consequence represents, to the top of our know-how, the widest instantaneous bandwidth received from a get more info Yb-fiber-laser-pumped singly resonant OPO, demonstrating the immense possible of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-speedy OPOs.
The chosen nonlinear crystals exhibit bigger nonlinear conversion performance when compared with AgGaS 2 , with BaGa two GeS 6 Furthermore presenting a narrower angular spectrum of spontaneous parametric down conversion, beneficial in interferometric strategies. Our findings build a pathway for integrating State-of-the-art crystal systems into mid-infrared metrology and imaging methods, placing the stage for potential developments in nonlinear interferometry and spectroscopy.
3% rms around twelve h in great beam high-quality. The in close proximity to-IR signal pulses from your OPO Have a very Gaussian pulse duration of �?19 ps , calculated at 1284 nm. We have now investigated the temperature tuning attributes from the OPO and when compared the data Along with the theoretical calculations working with The newest Sellmeier equations and thermo-optic coefficients to the crystal. To the top of our awareness, this is the initially picosecond OPO depending on CSP functioning at MHz repetition costs.
