Description
Technical field
The utility model relates to laser device field, particularly relates to a kind of laser diode.
Background technology
Laser diode comprises single heterojunction, double heterojunction and quantum-well diode laser.It is low that quantum-well diode laser has threshold current, the advantage that power output is high, is the main product of existing market application.Compare with laser, laser diode has the advantage that efficiency is high, volume is little, the life-span is long, but its power output is little, linearly poor, monochromaticjty is not so good, its application in cable television system is very limited, can not multichannel be transmitted, high performance analog signal.In the passback module of two-way light receiver, up transmitting generally all adopts quantum-well diode laser as light source.Usually select the working temperature of laser diode by means of a kind of thermoelectric control device and keep constant, and by the operating current changing laser diode, the laser emission of being launched by laser diode being adjusted.When using laser diode structure in gas sensor technology, such as required in adjustable diode laser spectrum method high detection sensitivity requires the laser emission that produced by laser diode structure with least interference phenomenon from laser diode outgoing.Even if the very little back reflection of the laser of the laser beam sent from laser diode on the reflecting surface of the shell of laser diode structure, collimating lens or exit window still has the effect from mixing of etalon effect and/or laser beam.These two kinds of effects produce optical noise, and optical noise can be reduced in the signal resolution in high-resolution testing apparatus, and has weak GAS ABSORPTION.
