We observed 7.2 dB squeezing of continuous-wave light at 860 nm with a periodically-poled KTiOPO4 crystal in an optical parametric oscillator. The squeezing level was obtained as the LO phase was locked.
A novel type of hybrid amplifier/wavelength converter is presented, coupling a TDFA and a FOPA module in series. Signal amplification over the entire S-Band (1450-1530 nm) and signal-to-idler conversion from 1540-1630 nm is demonstrated.
A compact multi-loop stretcher system with a pulse confining structure was demonstrated. This system generated chirped pulse with 32 ps/nm chirp rate. The energy loss in the stretcher was compensated by the OPCPA.
Nonlinearity management is explored as a multilevel tool to obtain maximum transmission reach in a WDM system. A technique for the fast calculation of the optimal dispersion pre-compensation in systems with distributed amplification is proposed.
Active mode-locking of a near degenerate (~1064 nm) doubly resonant periodically poled LiNbO3 OPO pumped at 532 nm is reported. Pulse durations as short as 700 ps are observed.
We show that the emergence of temporally stable component in SBS Stokes emission excited by CW monochromatic pump radiation in optical fiber is a manifestation of the phenomenon of spectral self-phase conjugation.
Self-similar propagation in a system of coupled amplified nonlinear Schrodinger equations is studied. Each individual equation can sustain a component similariton and their incoherent summation leads to an incoherent parabolic similariton under a width-matching condition.
We have developed a vectorial quantum model of spontaneous parametric down-conversion in one-dimensional nonlinear photonic-band-gap structures that shows that these structures represent a promising perspective source of entangled two-photon states.
We report optical parametric generation and amplification in BiB3O6. Using 420 muJ, 35-ps pump pulses at 532 nm, signal and idler output pulse energies of 120 muJ have been generated at 29% efficiency.
We demonstrate engineered refractive index profiles for the mitigation of nonlinear optical impairments such as stimulated Raman scattering and stimulated Brillouin scattering. These fibers offer performance improvements over conventionally used large mode area fibers.
We demonstrate the generation of near-Fourier-limited 9.8 plusmn 0.3 fs laser pulses with an intensity exceeding a terawatt at 30 Hz repetition rate, using noncollinear optical parametric chirped pulse amplification. Amplified fluorescence is kept below 1%.
We use phase-matched four-wave mixing in appropriately designed silicon waveguides to demonstrate amplification over a 29 nm range and efficient wavelength conversion in the range from 1511 nm to 1591 nm.
High-harmonic generation is achieved at 100 MHz repetition rates by utilizing a femtosecond enhancement cavity to increase peak intensities from a mode-locked laser. This provides a coherent frequency comb in the VUV for high-resolution spectroscopy.
We show an enhanced effect of cross-phase modulation with a Raman amplifier configuration. High performance wavelength conversion of 10 Gb/s non-return-to-zero signal is demonstrated with cross-polarization-modulation and Raman enhancement.
We present first experimental results of a non-degenerate single-pass Cr:forsterite optical parametric chirped pulse amplification in periodically poled stoichiometric LiTaO3 at 1 kHz, which delivers muJ-pulses near 935 nm and 1235 nm, respectively.
200TW peak power at 45 fs pulse duration (910 nm central wavelength) has been achieved experimentally using three optical parametrical amplifiers based on KD*P crystals. Energy conversion efficiency of the final amplifier stage was 25%.
This study shows the optical properties of a vertical cavity laser(VCL) - depleted optical thyristor(DOT) fabricated using selective oxidation. The oxide confined PnpN VCL-DOT clearly shows the nonlinear s-shaped current-voltage and lasing characteristics.
We report an optical parametric oscillator/power amplifier using periodically poled MgO:LiNbO3 with 38 mm length and 5times5 mm2 large aperture. We achieved output energy of 52 mJ with spectral bandwidth of <2 nm at degeneracy point (2.128 mum).
We report a new method for carrier-envelope-phase determination, based on electro-optical detection of the THz pulse emitted from a plasma generated by the few-cycle pulses being characterized.
We report optical parametric amplifiers using asymmetric Y-junctions, which launch the pump in a pure TM10 mode and separate the signal and idler in the TM10 and TM00 modes with 2 . d power contrast ratios.
