介绍了一种简单、低成本的激光联锁装置，它通过ESP 32微控制器发出的软件命令进行操作。该装置的结构被构造成确保在来自激光器外壳的互锁信号线上的开路或装置断电的情况下关闭激光器输出。通过否决本地控制（例如键盘）来防止无意中暴露于激光束，直到外壳重新联锁并且用户主动干预。该设备旨在关闭Spectra-Physics Millennium Pro泵浦激光器的机械快门，同时继续内部运行。硬件和编码是通用的，只需对代码进行微小的编辑，就可以在任何通过串行接口接收软件命令的仪器上部署该设备。
A simple and low-cost laser interlock is presented that operates via software commands issued by an ESP32 microcontroller. The architecture of the device is constructed to ensure the laser output is shut off in the event of either an open circuit on the interlock signal line from the laser enclosure or loss of power to the device. Unintentional exposure to the laser beam is prevented by overruling local controls (such as a keypad), until both the enclosure is re-interlocked and the user actively intervenes. The device presented is designed to close the mechanical shutter of a Spectra-Physics Millennia Pro pump laser while it continues to operate internally. The hardware and coding are versatile enough that only minor edits to the code would be necessary to deploy the device on any instrument that receives software commands via a serial interface.
