摘要： A laser diode mount having a thermal coupling for a laser diode heat sink utilizes a shape memory alloy in the maintaining of laser diode arrays within an operational temperature bandwidth. A diode carrier member holds a laser diode array and is movably attached with posts to a heat sink and spaced by a variable air gap from the heat sink thermal pad. The diode carrier member can move on the posts to vary the gap and a shape memory alloy member is shaped as a coil or spring and coupled between the diode carrier member and the heat sink thermal pad for use in varying the gap therebetween. The shape memory alloy member works against a conventional spring. The heat sink thermal pad may be part of a forced convection heat sink. The shape memory alloy allows for a variable thermal impedance by the self-regulation of an air gap thickness between a laser diode array and the heat sink which allows a rapid warm-up of the diodes by providing thermal isolation from the heat sink during warm-up and then control of the heat transfer to the heat sink when the diodes reach their normal operating temperature.

摘要： A diode laser structure is thermally stabilized by passing current through heater strips along the sides of the diode laser cavity. The thermally stabilized diode laser structure comprises a first confinement layer and a substrate of one conductivity type, an active layer, a second confinement layer and a contact layer of an opposing conductivity type. Disordered regions extend from the contact layer through to the first confinement layer defining diode laser cavities. Resistive regions are formed within the disordered regions. Individual contacts on the contact layer aligned with each diode laser cavity inject current through the diode laser cavity to the contact on the substrate causing emission of coherent light through the edge of the diode laser structure. Individual contacts on the contact layer aligned with resistive region inject current through the resistive region to the contact on the substrate causing generation of heat. The resistive region within the disordered region forms a heater strip and adjacent heater strips maintain the temperature within the diode laser cavity inbetween the adjacent disordered regions of the heater strips. The resistive can be replaced with a diffused region to provide a forward biased p-n junction to form the heater strip. The contacts for the laser cavity and the heater strips can be interdigitated.

摘要： A method and portable apparatus for measuring particulate concentration in the atmosphere utilizing uniform laser pulses to traverse the atmosphere to be measured and a photo-electronic receiver which discriminates against stray light and detects the attenuation of the laser pulses. This attenuation is caused by particulates in the atmosphere which tend to scatter or absorb light. By using monochromatic laser pulses having wavelengths lying in transparent atmospheric windows, error is not introduced by the attenuation of the beam due to gases occurring naturally in the atmosphere including water vapor. Thus concentration of particulates such as smoke, fog, smog, dust and the like are measurable.

摘要： A light source unit for thermally-assisted magnetic head includes a substrate member having a first bonding surface; a light source assembly attached on the first bonding surface of the substrate member and having a second bonding surface; and a heater circuit assembly formed between the substrate member and the light source assembly, the heater circuit assembly having a heater formed on the substrate member and two leads connected at two ends of the heater, the lead being thicker than the heater, thereby a distance between the heater and the second bonding surface is farther than that between the lead and the second bonding surface. The light source unit can reduce mechanical stress and thermal conduction between a light source assembly and a substrate member, thereby improving the performance of the light source assembly and the heater.

摘要： A method (700) of biasing a tunable laser (310) during burst-on and burst-off states includes receiving a burst mode signal (514) indicative of the burst-on state or the burst-off state and when the burst mode signal is indicative of the burst-on state: delivering a first bias current (IGAIN) to an anode of a gain-section diode (590a) disposed on a shared substrate of the tunable laser; and delivering a second bias current (IPH) to an anode of phase-section diode (590b) disposed on the shared substrate. The second bias current is less than the first bias current. When the burst mode signal transitions to be indicative of the burst-off state, the method also includes delivering the first bias current to the anode of the gain-section diode; and delivering the second bias current to the anode of the phase-section diode wherein the first bias current is less than the second bias current.
