Title: Stripe laser and method for making same
Inventor: COLLOT PHILIPPE
IPC: H01S5/223
Filed: 1998-11-03
Abstract: The invention concerns a stripe laser comprising: a substrate (1) whereof one surface is provided with at least a sunk or wire-shaped mesa relief in the form of a stripe; several stacks of layers located on said surface, each stack comprising a first confinement layer (2), an active laser layer (3), a second confinement layer (4); a contact layer (5) located on the top stack; an electrode (6) located on the contact layer (5); the longitudinal edges of said relief producing a longitudinal optical guidance in each active layer of each stack. Such a laser constitutes a power laser with high luminance, for timed or quasi-continuous operation in the near infrared (GaAs and InP dies). The strong luminance results from the use of a compact stacking of laser layers electrically associated with Esaki diode junctions. The stacking can realistically comprise up to five emissive stages with a repeat step close to 3 νm. With such devices, it is most likely that peak optical densities on the transmitter of the order of 100 kW.cm-2 can be achieved, which would represent an improvement of factor 100 of current performances at present. The main fields of application are: optical pumping of solid lasers, the iron industry and illuminators.
