摘要	A method is provided for maintaining the temperature of a laser diode located in a laser package. The method begins by monitoring a photocurrent generated by a photodiode that collects light from a back-facet of the laser diode located in the laser package while maintaining a constant bias level to the laser diode. Next, the laser diode is heated or cooled to maintain a substantially constant photocurrent, thereby maintaining the temperature of the laser diode at a substantially constant value. The laser package may be an uncooled laser package such as a coaxial can laser package.
其他摘要	提供一种用于维持位于激光器封装中的激光二极管的温度的方法。该方法首先监测由光电二极管产生的光电流，该光电二极管从位于激光器封装中的激光二极管的背面收集光，同时保持对激光二极管的恒定偏置电平。接下来，激光二极管被加热或冷却以保持基本恒定的光电流，从而将激光二极管的温度保持在基本恒定的值。激光器封装可以是非冷却激光器封装，例如同轴罐激光器封装。
