Generation of a stable low-frequency squeezed vacuum field with periodically poled KTiOPO4 at 1064 nm.
We report the generation of a stable continuous-wave low-frequency squeezed vacuum field with a squeezing level of 7.4+/-0.1 dB at 1064 nm, the wavelength at which laser-interferometric gravitational wave (GW) detectors operate, using periodically poled KTiOPO4 (PPKTP) in a subthreshold optical parametric oscillator. The squeezing was observed in a broad band of frequencies above 700 Hz where t...
متن کاملSub-shot-noise measurement with fiber-squeezed optical pulses.
A squeezed vacuum can enhance the sensitivity of an interferometric measurement limited by shot noise. By injecting a squeezed vacuum into the unexcited port of a phase-measuring device, and by orienting the squeezed vacuum so that its quiet quadrature is along the signal direction, the signal-to-noise ratio is improved. This was shown theoretically' 2 and demonstrated experimentally for measur...
متن کاملGeneration of mode-locked optical pulses at 1035 nm from a fiber Bragg grating stabilized semiconductor laser diode.
We report the generation of transform-limited, ~18 ps optical pulses from a fiber Bragg grating (FBG) stabilized semiconductor laser diode. Up to 7.2 pJ of pulse energy and a peak power of 400mW were achieved when operating at a repetition frequency of 832.6 MHz, a multiple of the cavity (diode + FBG) free spectral range (FSR). A small detuning in the repetition frequency resulted in broader op...
متن کاملGeneration of strongly squeezed continuous-wave light at 1064 nm.
A compact and effcient source of amplitude-squeezed light is described. It employs a semi-monolithic degenerate MgO:LiNbO(3) optical parametric amplifier pumped by a frequency-doubled Nd:YAG laser at 532 nm. Injection-seeding of the amplifier by a 1064 nm wave permits active stabilization of the cavity length and stable operation. At a pump power of 380 mW, a maximum noise reduction of 6.5 dB i...
متن کاملGeneration of 20 GHz, sub-40 fs pulses at 960 nm via repetition-rate multiplication.
Optical filtering of a stabilized 1 GHz optical frequency comb produces a 20 GHz comb with approximately 40 nm bandwidth (FWHM) at 960 nm. Use of a low-finesse Fabry-Pérot cavity in a double-pass configuration provides a broad cavity coupling bandwidth (Deltalambda/lambda approximately 10%) and large suppression (50 dB) of unwanted modes. Pulse durations shorter than 40 fs with less than 2% res...
