Proper Handling and Operation of Diode Lasers

Diode lasers are highly susceptible to damage from ESD and from temperatures exceeding their specified safe operating range. The user is advised to use care and proper ESD safety practices when handling them to avoid damage to the laser. A properly rated low noise current source, a low thermal resistance mount and a temperature controller should be used for optimal device performance and reliability.
