Title: Diode-pumped laser amplifier
Inventor: HOLLEMANN GUNTER
IPC: G02B13/08
Filed: 2001-08-02
Granted: 2008-05-20
Abstract: The object in the case of a diode-pumped laser amplifier is to increase the tolerance of the amplifier arrangement relative to variations of the input parameters significantly, so that fine-tuning is no longer necessary for guaranteeing the stability of the amplifier. Into a laser-active solid-state medium where a thermal lens of a strength which is different in orthogonal planes is generated in consequence of the irradiated pump radiation, a laser beam to be amplified is directed into the laser--active solid-state medium while being focused in the plane with a strong thermal lens, wherein a beam waist that is being generated lies in the area of the thermal lens. The laser amplifier can be used for amplifying the radiation of an oscillator.

Granted: 2008-03-11
Abstract: An end-to-end call identifier (EECID) is provided to uniquely identify a call leg across a packet network, regardless of the number of nodes used in completing the network path. The EECID allows for call association with a bearer connection so that high level call processing and low level bearer connection management can function independently but correlated by media gateways (309, 310, 414, 415) and media gateway controllers (301, 302, 401, 402).  Either a media gateway or media gateway controller can generate (502, 603) the EECID before establishing (504, 505, 604) a connection for a call. The EECID is then sent (503, 603, 604) to remote media gateways and media gateway controllers. The bearer connection can be setup by a media gateway at either end of the connection with respect to where the EECID is generated. The invention is useful in a connection oriented packet network that is connected to a TDM telephone network through a media gateway controlled by a media gateway controller.
