Applications in medical technology, printing, and safety technology (IR illumination) require powerful laser diodes that have a longitudinal single-mode beam profile.
Arima Lasers’ ADL-83Y51TL is a very good and inexpensive laser diode that is used, for example, in gesture recognition.
The ADL-83Y51TL emits in the NIR range at 830 nm and has a cw power of 250 mW. In pulse operation, it can be overdriven to up to 500 mW.
The small, compact TO-56 housing is hermetically sealed and allows for an operational temperature of up to 60°C. A monitor photodiode is integrated for power control and stabilization purposes.
