Title: Single dominant spike output erbium laser
Inventor: COZEAN COLETTE
IPC: H01S3/092
Filed: 2000-07-26
Abstract: A non Q-switched erbium laser (100) operating on the I11/2 I13/2 transition produces laser output pulses (190) characterized by a single spike (200) containing approximately 90% of the energy, rather than a series of multiple spikes (300). The laser (100) includes an optical gain medium (110) with erbium being the lasing species, such as an erbium doped YAG rod. The gain medium (110) is pumped with a flashlamp (130), with the voltage applied to the flashlamp (130) and the duration of the applied voltage being carefully controlled to produce the single spike laser output. Depending upon the operating conditions, the full width half maximum (FWHM) of the spikes can be varied between 0.1 and 10 microseconds. The output of the erbium has fewer than 10 transverse modes. Output from the erbium laser (100) may be directed onto corneal tissue in a preferred corneal sculpting procedure, in which the ablation rate is limited to no more than about 3 microns per laser pulse.

Abstract: The balanced, retractable dipole antenna comprises a first radiator element that is selectively extendable from, and retractable into, a mobile phone casing, a second radiator element, and a counterpoise that is electrically isolated from a printed wire board (PWB) of a mobile phone. The balanced, retractable dipole antenna further comprises a signal balancing means coupled between a signal source and at least the second radiator element and counterpoise to generate first and second signals, respectively. The first and second signals are substantially equal in magnitude but out of phase by 180 degrees. When the first radiator is extended, the first signal is transferred to the first and second radiator elements, and the second signal is transferred to the counterpoise. When the first radiator element is retracted, the first signal is transferred to the second radiator, while the second signal is transferred to the counterpoise and the first radiator element. The first and second signals produce balanced currents, thereby producing a symmetric radiation pattern.

IPC: H04J14/02
Filed: 1998-08-20
Abstract: A communications network has a plurality of nodes interconnected by an optical transmission medium. The transmission medium is capable of a carrying a plurality of wavelengths organized into bands. A filter at each node for drops a band associated therewith and passively forwards other bands through the transmission medium. A device is provided at each node for adding a band to the transmission medium. Communication can be established directly between a pair of nodes in the network sharing a common band without the active intervention of any intervening node. This allows the network to be protocol independent. Also, the low losses incurred by the passive filters permit relatively long path lengths without optical amplification.
