4400 SERIES FEATURES

The 4400 Series LaserSource laser diode driver is designed for demanding, high-power laser applications. With up to 100 Amps of drive current and high voltage configurations, the 4400 can meet many high power laser requirements. Add in the QCW operation, digital I/O, and temperature monitoring, and you have a very capable instrument.

The LaserSource has all the features you would expect from a laser driver, such as safety interlock, ESD protection, and hardware limit circuits for current and voltage.

In addition, the LaserSource has unique features not found on competing products including optically isolated modulation and photodiode inputs, programmable PD bias, and a constant voltage control mode

PILOT LASER CONTROL

Constant current or constant voltage operating modes

OVERLAPPING LASER PROTECTION

Including safety interlock, ESD protection, hardware limits for current & voltage, soft power-on, and intermittent contact safeguards.
