Particular embodiments disclosed herein provide a surgical laser system comprising a laser source, a lens, a memory, and a processor in data communication with the memory and configured to execute instructions, the instructions cause the processor to control the laser light source based on a detection signal received from a circuit. The circuit includes a first amplifier, a second amplifier, and a switch coupled between the second amplifier and a reference potential node, and a state of the switch is based on an output of a first comparator. The circuit further includes a second comparator coupled to the second amplifier and a logic gate coupled to the first comparator and the second comparator. 本文披露的特定实施例提供了一种手术激光系统，所述手术激光系统包括激光源、透镜、存储器以及处理器，所述处理器与所述存储器进行数据通信并被配置成执行指令，所述指令使所述处理器基于从电路接收的检测信号来控制所述激光源。所述电路包括第一放大器、第二放大器和开关，所述开关耦接在所述第二放大器与基准电位节点之间，并且所述开关的状态是基于第一比较器的输出。所述电路进一步包括耦接到所述第二放大器的第二比较器以及耦接到所述第一比较器和所述第二比较器的逻辑门。
