053 μm. The absorption spectrum of ammonia was introduced to demonstrate the feasibility in the formulated optical parametric oscillator system for spectroscopic measurements and gas detection.

Output idler energies within the microjoule stage are acquired with optimum conversion efficiency of eleven% to the amplifier stage, that is over two periods a lot better than the outcome attained having an analogous sample of the commonly spread materials AgGaS two .

In addition to the compactness and benign functioning attributes, it absolutely was the big adaptability in design and style and output characteristics that led on the success of solid-condition lasers during the last 40 yrs.

An easy technique for minimizing the loss that is because of depolarization resulting from thermally induced worry birefringence in solid-state lasers is documented. The system utilizes just one intracavity quarter-wave plate with its rapid or sluggish axis aligned parallel to the preferred aircraft of polarization, described by an intracavity polarizer.

With this work, we existing what's, to our know-how, the primary measurements on the quantum section diffusion sounds of a cw OPO. Read through much more

A method is made to solve the procedure of shortened equations describing parametric era in a 1-frequency OPO cavity below nanosecond pulsed pumping. The frequency conversion coefficient for ZnGeP2, AgGaSe 2, and HgGa2S4 crystals plus the best reflection coefficient in the output mirror are believed vs . the pump Electricity density Wp at distinctive values of your OPO nonstationarity .

Modeling and experimental analyze on stage matching of next harmonic generation in different colour Hg Ga 2 S four crystals are completed. Utilizing the regarded Sellmeier equations, the dispersion relation with weighting proportionally to brief-wavelength boundary with the crystal transparency band is proposed.
