and operating disorders for the sensible design and style of high electric power femtosecond optical parametric oscillators with excitation

Benefits of thermal conductivity measurements are documented for numerous of the greater a short while ago made nonlinear optical crystals. New or significantly revised values of thermal conductivity ended up received in six supplies. Noteworthy thermal conductivities calculated have been These for AgGaS2 [0.014 W/(cm K) and 0.

Apart from the compactness and benign operating characteristics, it had been the big overall flexibility in style and output attributes that led to the accomplishment of strong-condition lasers over the past 40 decades.

A simple technique for minimizing the reduction that is because of depolarization ensuing from thermally induced pressure birefringence in good-point out lasers is reported. The approach takes advantage of an individual intracavity quarter-wave plate with its rapidly or gradual axis aligned parallel to the popular aircraft of polarization, defined by an intracavity polarizer.

Self-referenced octave-large subharmonic GaP optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser

PA Ref-cell, which appreciably reduces themeasurement errors of your methane focus in thecase of instability

The generation of tunable pico- and femtosecond light pulses with parametric frequency conversion processes has captivated elevated consideration recently1. New crystal products, as BBO, LBO, and KTP, with superior nonlinearity and higher hurt threshold are actually readily available, and pump lasers of enhanced steadiness enable the responsible Procedure of optical parametric oscillators. Parametric products pumped ... [Exhibit whole abstract] either by cw modelocked lasers or by one extreme ultrashort pulses happen to be created. Within this contribution parametric systems are discussed that are pumped by extreme pulse trains of some microseconds period and repetition costs approximately 50Hz.

A method is developed to resolve the process of shortened equations describing parametric technology inside of a a person-frequency OPO cavity beneath nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals plus the optimum reflection coefficient of your output mirror are believed vs . the pump Electrical power density Wp at distinctive values in the OPO nonstationarity .

Examination of latest, promising broad-band-hole nonlinear crystals for your mid-IR is supplied. We centered on ternary and quaternary chalcogenides and based mostly on their own physical and chemical Attributes, which As well as linear and nonlinear optical Attributes, decide the effectiveness of crystal usage in specified laser experiments. The correlation between the composition, construction and output parameters and also the trends in alterations of the main qualities for instance band gap, nonlinear susceptibility, laser problems threshold, etcetera, are demonstrated.

... The initial details around the refractive index of orange HGS released by Levine et al. [35] here integrated only several wavelengths in the noticeable and in the vicinity of-IR just as an illustration with the feasibility of this crystal for birefringent stage-matching. The refractive indices for the orange stage ended up calculated and tabulated in between 0.

The observed file -to- 2 file frequency beats, originating directly from the OPO, can be employed for self-referencing and period locking from the pump laser comb without having for supercontinuum era. With an average output ability of �?thirty mW , this setup might be valuable for various spectroscopic applications from the mid-IR.

A simple quantum product agrees very well Along with the experimental benefits and makes it possible to interpret the outcome with regard to

three% rms above twelve h in excellent beam high-quality. The around-IR signal pulses from the OPO have a Gaussian pulse length of �?19 ps , measured at 1284 nm. Now we have investigated the temperature tuning characteristics on the OPO and as opposed the info Using the theoretical calculations working with The latest Sellmeier equations and thermo-optic coefficients for your crystal. To the most effective of our expertise, Here is the very first picosecond OPO determined by CSP operating at MHz repetition prices.
