20100183039 | TWO-DIMENSIONAL DIODE-LASER ARRAY WITH BROAD-BAND OUTPUT - It is demonstrated that substantial operating-parameter-dependent temperature-differences can exist between diode-laser bars in pulsed operation of a stack of such bars arranged to provide a two-dimensional array of diode-laser emitters. These differences can produce distortion of the aggregate output spectrum of the stack. By selecting particular nominal emitting wavelengths of the diode-laser bars for specific positions in the stack, the aggregate emission-spectrum can be tailored to a desired shape for one or more sets of operating parameters of the stack. | 07-22-2010 |
20110082447 | LENSED DUAL-CHIP FIBER-COUPLER FOR PROVIDING AN AIMING BEAM IN AN INFRARED RADIATION DELIVERY APPARATUS - Laser treatment apparatus includes one diode-laser providing infrared radiation for the treatment and another diode-laser for providing visible radiation. A lens launches the infrared and visible radiations from the diode-lasers into the entrance face of the optical fiber for transporting the radiations to a treatment location. | 04-07-2011 |
20120263201 | BROAD-AREA EDGE-EMITTING SEMICONDUCTOR LASER WITH LIMITED THERMAL CONTACT - A diode-laser having an elongated diode-laser emitter is mounted on a relatively massive heat-sink. Two parallel grooves are machined into the heat-sink to leave a relatively narrow elongated ridge of the heat-sink between the grooves. The ridge has a width about equal to or narrower that the width of the emitter. The diode-laser is mounted on the heat-sink such that thermal communication between the emitter and heat-sink is essentially limited to thermal communication with the ridge. | 10-18-2012 |
20130148679 | OPTICAL PUMPING OF A SOLID-STATE GAIN-MEDIUM USING A DIODE-LASER BAR STACK WITH INDIVIDUALLY ADDRESSABLE BARS - A diode-laser bar stack includes a plurality of diode-laser bars having different temperature dependent peak-emission wavelengths. The stack is arranged such that the bars can be separately powered. This allows one or more of the bars to be “on” while others are “off”. A switching arrangement is described for selectively turning bars on or off, responsive to a signal representative of the temperature of the diode-laser bar stack, for providing a desired total emission spectrum. | 06-13-2013 |
20140119393 | MACRO-CHANNEL WATER-COOLED HEAT-SINK FOR DIODE-LASER BARS - A diode-laser bar is mounted on water-cooled heat-sink between two ceramic sub-mounts for electrically isolating cooling-water in the heat-sink from the diode-laser bar. Mounting between the two ceramic sub-mounts also provides for balancing stresses due to differences in coefficient of thermal expansion (CTE) between the sub-mounts and the diode-laser bar. Both sub-mounts are in thermal communication with the heat-sink for providing two-sided cooling of the diode-laser bar. | 05-01-2014 |
20140119394 | MACRO-CHANNEL WATER-COOLED HEAT-SINK FOR DIODE-LASER BARS - A water-cooled heat-sink for a diode-laser bar includes a copper-cooling-unit having an integral mount thereon for the diode-laser bar. The copper-cooling-unit is attached to a steel base-unit. The base-unit and the cooling-unit are cooperatively configured such that at least one cooling-channel is formed in the cooling-unit by the attachment of the base-unit to the cooling-unit. The cooling-channel is positioned to cool the mount when cooling-water flows through the cooling-channel. | 05-01-2014 |
