We produce superior-order harmonics from crystalline solids employing a tunable mid-IR OPA with 50 kHz repetition rate. Utilizing nonlinear self-compression in YAG crystals, we make sub 3-cycle pulses at three.8 μm wavelength for prime harmonic spectroscopy. Examine more

Due to the great extensive efficiency plus the essential application price in laser field, they've attracted much notice in your house and overseas. The progress of crystal growth and laser output of BGSe and BGGSe are summarized, and the long run development is prospected.
Throughout the past a long time, mid-infrared (3–12 μm) laser sources utilizing crystals with nonlinear optical Attributes have attracted a particular awareness due to their potential programs in various fields including optical counter-measures and remote chemical sensing. As transparency of typical oxide crystals is restricted to about 4 μm, many researches have already been centered on chalcopyrite compounds thanks to their broad transparency inside the mid-IR selection as well as their potent nonlinear optical coefficients. There exists a have to have of these kinds of crystals able to convert successfully the close to infrared wavelengths from commercially out there lasers into wavelengths higher than five μm through Optical Parametric Oscillators (OPO) methods.

A top quality BGGSe one crystal with dimensions of thirty mm×ninety mm was developed by Bridgman-stockbarger system, which can be the very first in China. The effective fabrication of BGGSe crystal products was also reached following orienting, reducing, and sharpening procedures, which laid a strong foundation with the more application research on the crystal.
The behavior of dislocations inside the interfacial region amongst the epitaxial layer developed within the liquid stage as well as substrate of GaAs is investigated. Observations of dislocations lying along the 〈one hundred ten�?Instructions were being performed using an optical microscope after shallow etching using a new chemical etchant.
46 m duration stuffed by CO2 at three atm gasoline force wherever the laser pulse was broadened as a consequence of self-period modulation beneath filamentation. Then, the pump and signal pulses were put together alongside one another. Some time correlation on the pump and signal pulses was managed through the pump pulse arm length from the adjustment of mirror M3 place.
The pump pulse Electrical power was managed by a variable diffraction attenuator. Its polarization was more info tuned by 90° that has a 50 percent-wave plate because it had to be ordinary wave during the BGGSe (when AGS crystal was utilised, the sign beam polarization was tuned). The signal beam was concentrated by spherical mirror (M2, the focal length of two m) right into a gas tube of 1.
