The CW output power is 20mW; pulse output power is 45mW. The Butterfly package includes an integrated photodiode, thermoelectric cooler, and temperature sensor. These lasers comes standard with FC/APC connector. Please contact us for information on fiber and fiber connector options.

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.
