and working circumstances for the sensible design of superior electricity femtosecond optical parametric oscillators with excitation
Outcomes of thermal conductivity measurements are described for a number of of the more not long ago designed nonlinear optical crystals. New or significantly revised values of thermal conductivity ended up acquired in 6 elements. Noteworthy thermal conductivities calculated were being All those for AgGaS2 [0.014 W/(cm K) and 0.
Besides the compactness and benign working options, it had been the big flexibility in style and design and output features that led towards the accomplishment of good-point out lasers throughout the last forty many years.
By implementing intracavity dispersion Handle, near-rework-restricted signal pulses of �?a hundred fs length with clean one-peak spectrum are attained at 1264 nm, comparable to an idler wavelength at 6440 nm. To the top of our know-how, This is often The 1st time these types of simple idler powers from the deep-IR have been created from a dispersion-compensated CSP femtosecond OPO at sub-a hundred MHz repetition amount.
We report new experimental success within the period-matching properties of yellow colour HgGa2S4 crystals for harmonic generation of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers inside the 0.944-ten.5910 μm range. Also, we existing new Sellmeier equations that provide a excellent replica from the present experimental effects in addition to the revealed facts details for next-harmonic technology of CO2 laser radiation at nine.
brought about oscillations from the idler wavelength of under 200MHz more than 300s; the short-expression stability was a lot less than 3MHz
When applying an institutional account for this website we don’t track any own, performance, useful or 1st or 3rd get together associated info.
A technique is produced to unravel the method of shortened equations describing parametric era in a a single-frequency OPO HgGa2S4 Crystal cavity less than nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals along with the exceptional reflection coefficient of the output mirror are estimated as opposed to the pump Electrical power density Wp at various values from the OPO nonstationarity .
The precise warmth and thermal conductivity of HgGa2S4 are calculated. It is actually concluded the mixed Houses of HgGa2S4 crystals can offer for them a number one posture among the components Utilized in nonlinear-optical units for mid-IR-frequency conversion.
The 3rd harmonic of CO2-laser radiation has long been obtained by passing the laser beam by way of two CdGeAs2 crystals in tandem, with the main crystal oriented for 2nd-harmonic technology and the 2nd for sum mixing. Making use of This system, Now we have attained a mean exterior conversion performance of one.
Interference is observed amongst the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
12 μm and explain all frequency conversion techniques realized to date with them together with long term likely apps. Key terms: Ternary and quaternary semiconductors, defect chalcopyrites, good alternatives, nonlinear optical crystals, mid-infrared
The selected nonlinear crystals show better nonlinear conversion effectiveness as compared to AgGaS two , with BaGa 2 GeS six Also giving a narrower angular spectrum of spontaneous parametric down conversion, advantageous in interferometric techniques. Our results set up a pathway for integrating State-of-the-art crystal technologies into mid-infrared metrology and imaging systems, placing the stage for upcoming developments in nonlinear interferometry and spectroscopy.
three% rms about twelve h in fantastic beam excellent. The in the vicinity of-IR sign pulses through the OPO Have a very Gaussian pulse length of �?19 ps , measured at 1284 nm. We have investigated the temperature tuning traits from the OPO and compared the info Along with the theoretical calculations employing the most recent Sellmeier equations and thermo-optic coefficients for that crystal. To the top of our awareness, This is actually the first picosecond OPO dependant on CSP working at MHz repetition premiums.
