With the arrival of new nonlinear resources and solitary-frequency pump sources, You can find renewed curiosity in optical parametric oscillators (OPOs). An individual-method diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is equally amplified and frequency doubled is accustomed to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
Benefits of thermal conductivity measurements are noted for various of the more just lately made nonlinear optical crystals. New or considerably revised values of thermal conductivity were received in 6 products. Noteworthy thermal conductivities measured have been All those for AgGaS2 [0.014 W/(cm K) and 0.
A set of ~450 noncentrosymmetric sulfides has become observed in reference to nonlinear optical Houses. It's been found that around the plane with the oxide bond lengths the noncentrosymmetric sulfide crystals are dominantly positioned right into a rosette of two intersected ellipses of «acentricity».
.. [Present full summary] third-harmonic technology and parametric amplification with reduced-frequency pumping in periodically poled Energetic nonlinear crystals also are investigated. The Investigation is carried out for the situation of the periodically poled Nd:Mg:LiNbO3 crystal. Views of utilizing periodically poled active nonlinear crystals in laser gadgets with self-frequency conversion are mentioned.
Self-referenced octave-large subharmonic GaP optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
The measured Main amount binding energies are in contrast with All those of HgS, GaS, AgGaS2 and SrGa2S4 compounds. The valence band spectrum proves for being independent within the technological circumstances of crystal growth. In distinction towards the valence band spectrum, the distribution of electron states in the bandgap of HgGa2S4 crystals is located for being strongly dependent upon the technological disorders of crystal development as demonstrated with the photoluminescence Evaluation.
The era of tunable pico- and femtosecond light-weight pulses with parametric frequency conversion procedures has attracted improved attention recently1. New crystal elements, as BBO, LBO, and KTP, with exceptional nonlinearity and high problems threshold are now offered, and pump lasers of enhanced stability allow the responsible operation of optical parametric oscillators. Parametric products pumped ... [Show entire summary] possibly by cw modelocked lasers or by one intensive ultrashort pulses happen to be formulated. During this contribution parametric devices are reviewed that happen to be pumped by more info intense pulse trains of some microseconds period and repetition prices around 50Hz.
We existing a numerical research for the design of economical MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with enter pump pulses of leading-hat transverse depth profile, plus a double-move pump cavity configuration. Particularly, we examine the influence of domain condition about the conversion efficiency. We thought of two varieties of domain buildings: "great vertical-wall" and "wedge-formed" domains and our numerical final results present that at bigger pump pulse energies, the conversion efficiency saturates, as well as the saturated efficiency is sort of independent from the area designs.
Increased-order nonlinear processes in option components also are deemed in addition to a dialogue on substance suitability for down-conversion of near-IR lasers in the mid-IR to meet different software prerequisites is likewise offered.
stabilize and tune the OPO, from which the sound etalon gave an even better overall performance. Temperature oscillations inside the PPLN crystal
The strategy is based on group velocity matching between interacting waves in addition to birefringent section matching. We are going to explain broadband SHG characteristics concerning beam propagation directions, spectral positions of resonance, efficient nonlinearities, spatial wander-offs among interacting beams, and spectral bandwidths. The effects will exhibit that the spectral bandwidths of the fundamental wave permitted for broadband SHG to reach many a huge selection of nm. The corresponding SH spectral array spans from 1758.58 to 4737.18 nm inside the non-oxide crystals thought of Within this examine. This sort of broadband SHG working with shorter pulse trains can probably be placed on frequency up-conversion imaging in the mid-IR region, in facts transmission, As well as in nonlinear optical sign processing.
Note: Author names will probably be searched inside the key terms industry, also, but which will come across papers where by the person is described, rather then papers they authored.
During this paper we theoretically examine quite possibly the most successful pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Investigation includes resolving the best Regulate dilemma using the level equation formalism. The OPO ideal buildup behavior is derived for virtually any OPO configuration, and we demonstrate that the best pump pulse shape is often a double rectangle. The initial rectangle is optimized for the buildup approach, whilst the 2nd 1 is optimized with the regular point out, and each count in a different way to the OPO mirror reflectivities along with the obtainable pump Strength and maximum peak electricity.
