We theoretically investigate the piezo-optic effect of high-harmonic generation (HHG) in shear-strained semiconductors. By focusing on a typical semiconductor, GaAs, we show that there is optical activity, meaning different responses to right-handed and left-handed elliptically polarized electric fields. also this activity more pronounced for higher harmonics whose perturbative order exceeds ba...

A three-axis magnetometer based on the nonlinear magneto-optic effect is described. The magnetometer was used to measure the average (over the cell volume) residual magnetic field and to determine the shielding ratio of a multi-layer magnetic shield. The shot-noise-limited sensitivity of the magnetometer is estimated to be ≈10 Gs/Hz. A possible application to parity and time reversal invariance...

Nonlinear optics is a branch of that explains the nonlinear response atoms and molecules to field light radiation. There difficulty in cutting crystals shapes commensurate with their optical properties, thus it was significant determine descriptive shape crystal properties based on its optic be ideal use. The problem determining length give best output power still under study research one most ...

We have studied the nonlinear Faraday effect with intense linear polarized light in an optically thick atomic rubidium vapor. We demonstrate that the polarization rotation rate rotation angle per unit magnetic field, in the limit of low field has a maximum value as the intensity and density are increased. We also show that the optimal sensitivity of an optical magnetometer based on this system ...

We reported a record high power (>250 mW) and compact near-infrared fiber-optic femtosecond Cherenkov radiation source and its new application on nonlinear light microscopy for the first time (to our best knowledge). The high power femtosecond Cherenkov radiation was generated by 1.03 μm femtosecond pulses from a portable diode-pumped laser and a photonic crystal fiber as a compact, flexible, a...

We have developed a technique for precise measurement of small magnetic fields using nonlinear magneto-optic rotation (NMOR). The technique relies on the resonant laser beam being chopped. During the on time, the atoms are optically pumped into an aligned ground state (Δm= 2 coherence). During the off time, they freely precess around the magnetic field at the Larmor frequency. If the on-off mod...

Experimental and theoretical investigation of a nonlinear response of a two-mode fiber interferometer to axial strain is described. It is discovered that the nonlinearity dramatically increases as the wavelength approaches the cutoff wavelength of the second-order mode (LP(11)).
