Product Overview:

1750nm Laser Diode, 40mW Output Power Overview

These 1750nm Fabry-Perot laser diodes are offered in a TO-9 or SOT-148 package. The rated output power in continuous wave (CW) operation is 40mW and these lasers can be pulsed for higher output power. The operating current is less than 300mA with a threshold at 70mA. The integrated photodiode allows for constant power control with compatible laser diode driver. The photodiode current is up to 100 µA.

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.
