摘要	A laser driver for a laser, which includes an adjustable DC-DC power source, an optical power control loop, and a power source voltage regulator. The adjustable DC-DC power source is coupled to the optical power control loop and the power source voltage regulator, in order to provide a working current for the laser. The optical power control loop is configured to adjust the output optical power of the laser to a set value for optical power by adjusting a working voltage of the laser, and to generate a power source voltage state indicator voltage. The power source voltage regulator is used to generate the power source setting voltage, so that the power source voltage state indicator voltage is greater than or equal to a first preset threshold, or less than or equal to a second preset threshold.
其他摘要	一种用于激光器的激光驱动器，包括可调节的DC-DC电源，光功率控制回路和电源电压调节器。可调节DC-DC电源耦合到光功率控制回路和电源电压调节器，以便为激光器提供工作电流。光功率控制环路被配置为通过调节激光器的工作电压将激光器的输出光功率调节到光功率的设定值，并产生电源电压状态指示器电压。电源电压调节器用于产生电源设定电压，使得电源电压状态指示电压大于或等于第一预设阈值，或小于或等于第二预设阈值。
