Proper Handling and Operation of Laser Diodes
Laser diodes are extremely susceptible to damage by electrostatic discharge and temperatures exceeding their specified safe operating range. It is recommended that users exercise caution and take appropriate ESD safety measures during handling to avoid damage to the laser. Properly rated low-noise laser diode current sources, low thermal resistance brackets/heat sinks, and temperature controllers should be used to ensure proper performance and reliability of the device.
