With the appearance of latest nonlinear materials and single-frequency pump sources, You can find renewed desire in optical parametric oscillators (OPOs). Just one-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is definitely both amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Success of thermal conductivity measurements are claimed for various of the greater just lately developed nonlinear optical crystals. New or substantially revised values of thermal conductivity were being received in 6 elements. Notable thermal conductivities measured ended up These for AgGaS2 [0.014 W/(cm K) and 0.
crystals with ultrafast Yb-ion laser pump is proposed. The outcome form a handy reference for the selection of components
Scientific tests of viable pump laser systems ideal for ultrafast femtosecond OPOs based upon CdSiP 2 are mentioned, along with the favorable linear and nonlinear optical Houses, and also one of a kind section-matching features of CdSiP two , are offered applying the most recent Sellmeier equations for the fabric. The described experimental benefits symbolize the highest output pulse Vitality and document average power from the ultrafast picosecond and femtosecond time scales over the 6–7 μm spectral variety thus far.
OPO have been improved by optimizing pump beam waist and OPO cavity length. Each air-spaced and stable etalons were being analyzed to frequency
This double rectangle is quantitatively described and it is per former outcomes described within the literature. Also, numerical simulations are accustomed to validate our analytical design with a doubly resonant OPO and present dependable benefits. The numerical simulations also clearly show that an ideal top-hat temporal profile could provide performances quite near to those realized with the optimal double rectangle.
Two parametric 4-wave-mixing (FWM) procedures in Rb atoms are analyzed applying perturbation idea underneath the affliction of rotating wave approximation. The 2 parametric FWM procedures are coupled when they are energized coherently by a brief laser pulse with a bandwidth encompassing the two corresponding higher energy degrees in The 2 FWM processes.
We current a numerical study for the look of efficient MgO:PPLN based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of prime-hat transverse intensity profile, along with a double-pass pump cavity configuration. In particular, we look into the influence of area form over the conversion efficiency. We considered two different types of area constructions: "great vertical-wall" and "wedge-formed" domains and our numerical final results demonstrate that at increased pump pulse energies, the conversion effectiveness saturates, and also the saturated performance is sort of independent with the domain styles.
Greater-order nonlinear procedures in choice supplies may also be regarded as well as a discussion on materials suitability for down-conversion of close to-IR lasers into your mid-IR to fulfill numerous application necessities can also be presented.
Assessment of latest, promising extensive-band-hole nonlinear crystals to the mid-IR is specified. We focused on ternary and quaternary chalcogenides and primarily based on their own Actual physical and chemical Qualities, which In combination with linear and nonlinear optical properties, decide the performance of crystal use in specific laser experiments. The correlation involving the composition, composition and output parameters together with the traits in changes of the key attributes for instance band hole, nonlinear susceptibility, laser injury threshold, and many others, are shown.
Interference is observed among the spontaneous parametric radiation from two nonlinear crystals divided by a macroscopic
We report a broadband optical parametric oscillator (OPO) pumped by a Yb-doped fiber laser technique. By employing a 300 μm extended magnesium-doped periodically poled LiNbO three crystal given that the parametric acquire medium and configuring the OPO being a chirped-pulse oscillator, we obtained mid-infrared emission owning an instantaneous bandwidth covering 3084�?466 nm. This outcome represents, to the top of our know-how, the widest instantaneous bandwidth attained from the Yb-fiber-laser-pumped singly resonant OPO, demonstrating the immense prospective of chirped-pulse oscillation in scaling the instantaneous bandwidth of ultra-rapidly OPOs.
A simple quantum model agrees very well Along with the experimental results and makes it probable to interpret the impact regarding
Variation frequency mixing of strongly concentrated Gaussian beams in periodically poled more info LiNbO3 was investigated. The beams were focused inside the crystal without having problems. Mixing of cw and pulsed laser units was utilized to reduce the thermal lensing consequences inside of this crystal. A small-energy cw 1.064‐μm Nd:YAG laser beam was used as the pump, Whilst the sign beam came from a picosecond optical .
