Optical parametric oscillator pumped at ~one µm with intracavity mid-IR distinction-frequency technology in OPGaAs
The significance in the obtained results lies in The truth that to have the similar conversion in SHG or DFM, 1 now necessitates basic input radiation with A lot decreased intensity.
In addition to the compactness and benign running features, it had been the enormous versatility in design and style and output features that led on the achievement of sound-condition lasers during the last forty many years.
A straightforward procedure for cutting down the reduction that is due to depolarization ensuing from thermally induced worry birefringence in sound-point out lasers is documented. The strategy utilizes one intracavity quarter-wave plate with its quickly or gradual axis aligned parallel to the popular airplane of polarization, described by an intracavity polarizer.
Self-referenced octave-huge subharmonic Hole optical parametric oscillator centered at three μm and pumped by an Er-fiber laser
PA Ref-mobile, which substantially lowers themeasurement faults of the methane concentration in thecase of instability
Two parametric 4-wave-mixing (FWM) processes in Rb atoms are examined utilizing perturbation idea beneath the condition of rotating wave approximation. The two parametric FWM processes are coupled when they are enthusiastic coherently by a brief laser pulse with a bandwidth encompassing the two corresponding upper Vitality concentrations in the two FWM processes.
We existing a numerical examine for the design of successful MgO:PPLN dependent pulsed nanosecond optical parametric oscillator (OPO), with input pump pulses of major-hat transverse intensity profile, along with a double-move pump cavity configuration. Specifically, we examine the outcome of area condition to the conversion effectiveness. We thought of two types of area structures: "perfect vertical-wall" and "wedge-formed" domains and our numerical outcomes demonstrate that at better pump pulse energies, the conversion effectiveness saturates, along with the saturated performance is sort of unbiased on the domain designs.
Higher-buy nonlinear processes in alternate resources will also be regarded as and a discussion on material suitability for down-conversion of in the vicinity of-IR lasers to the mid-IR to fulfill a variety of software needs is also offered.
This paper assessments the the latest developments in crystal development and singly resonant optical parametric oscillators for that technology of higher solitary pulse energy and normal powers in the mid-IR from three to 10 μm.
Easy approach for lessening the depolarization decline ensuing from thermally induced birefringence in solid-state lasers
Note: Creator names will likely be searched inside the keyword phrases subject, also, but that will uncover papers in which the person is stated, rather than papers they authored.
On this paper we theoretically look into probably the most economical pump temporal shape for pulsed Procedure of optical parametric oscillators (OPOs). The theoretical Examination includes fixing the optimal Command dilemma utilizing the amount equation formalism. The OPO best buildup conduct is derived for just about any OPO configuration, and we present that the optimum pump pulse shape is actually a double rectangle. The very first rectangle is optimized for the buildup course of action, although the next a single is check here optimized for that continual condition, and both equally depend in a different way to the OPO mirror reflectivities in addition to the accessible pump Electricity and most peak electrical power.
Diode-pumped optical parametric oscillation is demonstrated for The 1st time to our awareness in just one Nd:MgO:LiNbO3 nonlinear crystal. The crystal is pumped by a semiconductor diode laser array at 812 nm. The Nd³�?ions take in the 812-nm radiation to produce 1084-nm laser oscillation.
