Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR distinction-frequency technology in OPGaAs

A manner-locked tunable dye laser has actually been produced which is synchronously pumped at large repetition rates from the doubled output of a method-locked Nd:YAG laser. The dye laser gives extreme pulses of 35 psec length which have been broadly tunable, of close to-completely transform-restricted bandwidth, and in time coincidence While using the pumping pulses.

This technique allows the operation of commonly tunable optical parametric oscillators2 (OPO) and subsequent big difference frequency generators3 producing tunable pulses of higher peak ability. The higher Electricity from the pump pulse trains has certain benefits for that operation of a synchronously pumped OPO, e.g., relaxed security specifications, along with the likely to operate with significant cavity losses (e.g. steel mirrors) enabling massive tuning ranges with just one set of mirrors and higher output-coupling things for pulse shortening.

A straightforward procedure for decreasing the reduction that is because of depolarization resulting from thermally induced pressure birefringence in stable-condition lasers is claimed. The method employs just one intracavity quarter-wave plate with its fast or slow axis aligned parallel to the popular plane of polarization, outlined by an intracavity polarizer.

During this work, we present precisely what is, to our awareness, the 1st measurements on the quantum period diffusion sounds of the cw OPO. Read more

triggered oscillations from the idler wavelength of under 200MHz more than 300s; the shorter-term stability was below 3MHz

Taxonomy, chemical bonding relations and nonlinear optical properties of noncentrosymmetric sulfide crystals

We existing a numerical analyze for the design of economical MgO:PPLN primarily based pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of major-hat transverse depth profile, along with a double-go pump cavity configuration. Especially, we examine the effect of domain condition around the conversion performance. We thought of two types of domain structures: "best vertical-wall" and "wedge-formed" domains and our numerical results show that at increased pump pulse energies, the conversion effectiveness saturates, and also the saturated performance is sort of unbiased of the area designs.

The precise warmth and thermal conductivity of HgGa2S4 are calculated. It is actually concluded which the combined Attributes of HgGa2S4 crystals can offer for them a number one place Among the many materials Employed in nonlinear-optical equipment for mid-IR-frequency conversion.

stabilize and tune the OPO, from which the strong etalon gave an even better performance. Temperature oscillations inside the PPLN crystal

The strategy relies on team velocity matching in between interacting waves Along with birefringent stage matching. We're going to describe broadband SHG traits concerning beam propagation directions, spectral positions of resonance, helpful nonlinearities, spatial stroll-offs in between interacting beams, and spectral bandwidths. The final results will exhibit which the spectral bandwidths of the elemental wave allowed for broadband SHG to succeed in several a huge selection of nm. The corresponding SH spectral vary spans from 1758.58 to 4737.eighteen nm from the non-oxide crystals deemed On this research. Such broadband SHG making use of short pulse trains can probably be placed on frequency get more info up-conversion imaging during the mid-IR region, in data transmission, and in nonlinear optical sign processing.

Note: Creator names will probably be searched while in the keywords and phrases field, also, but that may find papers where the individual is outlined, as an alternative to papers they authored.

Solitary-stage sub-200 fs mid-infrared generation from an optical parametric oscillator synchronously pumped by an erbium fiber laser

This can be the initially example of a broadband OPO operating throughout the molecular fingerprint area, and we demonstrate its possible by conducting broadband Fourier-change spectroscopy utilizing water vapor and a polystyrene reference normal.
