20100085994 | ULTRASHORT SEED-PULSE GENERATING LASER WITH INTEGRAL PULSE SHAPING - An ultrafast laser for delivering ultra-short duration seed-pulses for further amplification has a resonator including negative group delay dispersion (NGDD) mirrors for minimizing increases in the duration of the pulses due to positive group delay dispersion effects inherent in the resonator. The NGDD mirrors could be configured such that the pulses had a Gaussian spectrum. Instead, however, the NGDD mirrors are configured and arranged such the pulses have a non-Gaussian spectrum. The non-Gaussian spectrum has a FWHM bandwidth significantly greater than that of the Gaussian spectrum. | 04-08-2010 |

20090290606 | MODE-LOCKED EXTERNAL-CAVITY SURFACE-EMITTING SEMICONDUCTOR LASER - A laser resonator includes an OPS gain-structure that is pumped with optical pulses repeatedly delivered at a pulse-repetition frequency corresponding to a resonant frequency of the laser resonator. The laser resonator additionally includes a passive mode-locking arrangement such that the resonator delivers mode-locked optical pulses. In one example the laser resonator further includes a CW optically pumped OPS gain-structure for increasing the power of the mode-locked pulses delivered from the resonator. | 11-26-2009 |

20080304127 | Non-fourier pulse-shapers including a combined pulse-shaper and pulse-compressor - A pulse-shaper for temporally shaping an optical pulse includes a prism or a grism arranged to disperse the optical pulse into a diverging fan of spectral-component rays. The fan of spectral-component rays is collimated by a lens or another grism. The collimated spectral-component rays are selectively modulated by a spatial-light-modulator (SLM). The modulated rays from the SLM are either recombined to form the temporally shaped pulse by another lens and another prism, another two grisms, or by the same lens and prism or the same two grisms. | 12-11-2008 |
20080310004 | Adjustable pulse-shaper - An optical pulse-shaper includes a prism, a delay line having positive optical power and a reflective spatial light modulator. In one arrangement the delay line has a selectively variable optical path length for accommodating pulses of different spectral bandwidth and positive optical power is provided by a concave mirror. In another arrangement, the delay line includes a zoom-mirror arranged to provide selectively variable optical power for accommodating pulses of different spectral bandwidth. | 12-18-2008 |
