With the appearance of new nonlinear elements and single-frequency pump sources, there is renewed fascination in optical parametric oscillators (OPOs). A single-mode diode-laser-pumped monolithic Nd:YAG nonplanar ring laser that is certainly both amplified and frequency doubled is utilized to pump a monolithic MgO:LiNbO3 pulsed singly resonant OPO.
A manner-locked tunable dye laser has been created which happens to be synchronously pumped at superior repetition fees via the doubled output of the method-locked Nd:YAG laser. The dye laser provides rigorous pulses of 35 psec length which can be widely tunable, of in the vicinity of-completely transform-confined bandwidth, As well as in time coincidence Together with the pumping pulses.

A simple procedure for decreasing the decline that is due to depolarization ensuing from thermally induced stress birefringence in reliable-point out lasers is claimed. The method employs only one intracavity quarter-wave plate with its quickly or sluggish axis aligned parallel to the preferred aircraft of polarization, outlined by an intracavity polarizer.
Self-referenced octave-wide subharmonic Hole optical parametric oscillator centered at 3 μm and pumped by an Er-fiber laser
PA Ref-mobile, which considerably minimizes themeasurement errors in the methane concentration in thecase of instability
The temperature dependence of refractive indices of optical resources is characterized Within this function by what we call their website normalized thermo-optic coefficients. These are decided experimentally by means of interferometric measurements of thermal enlargement and of improvements in optical thickness at several laser wavelengths as functionality of temperature. An acceptable vectorial formalism applied to these details makes it possible for predicting the thermal evolution of the refractive index all around the practical array of transparency.
air gap and psyched in series by a standard pump beam. The period from the interference depends on the period shifts at three frequencies.
Modeling and experimental examine on stage matching of second harmonic generation in various shade Hg Ga 2 S 4 crystals are performed. Using the recognized Sellmeier equations, the dispersion relation with weighting proportionally to limited-wavelength boundary in the crystal transparency band is proposed.
This paper critiques the new developments in crystal development and singly resonant optical parametric oscillators for your era of substantial one pulse Strength and common powers from the mid-IR from three to 10 μm.
... The very first facts around the refractive index of orange HGS revealed by Levine et al. [35] bundled only handful of wavelengths from the obvious and close to-IR just as an illustration of the feasibility of this crystal for birefringent phase-matching. The refractive indices for your orange stage have been calculated and tabulated involving 0.
The noticed file -to- two file frequency beats, originating straight from the OPO, may be used for self-referencing and stage locking of your pump laser comb without having for supercontinuum technology. With an average output electric power of �?30 mW , this set up could possibly be useful for various spectroscopic purposes from the mid-IR.
A simple quantum product agrees properly With all the experimental results and causes it to be feasible to interpret the outcome concerning
Tuning and stability of the constant-wave mid-infrared high-ability single resonant optical parametric oscillator
