The 4400 Series LaserSource is a high-accuracy laser driver capable of supplying
up to 100A for high-power laser and LED applications. This laser driver offers
QCW operation, digital I/O, temperature monitoring and industry leading laser
protection systems.

PILOT LASER CONTROL

Auxillary I/O
Z Two Temperature Sensors
Z Digital I/O
Z One Form-C Relay Contact
USB / RS-232 Interface
Z USB / RS-232 Connections

Constrant 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.

QUASI-CONSTANT WAVE MODE
QCW mode provides low duty cycle, high current pulses to manage
thermal loading. Pulse widths as narrow as 100 µs.

ANALOG MODULATION
Bandwidths up to 40 kHz.
C PV

MULTIPLE OPERATING MODES
Choose from:  Constant Current  Constant Power  Constant Voltage

1 23SIMPLE USER INTERFACE
Easy to Read, High Contrast VFD Display with all messages andsettings in plain English. View All 3 At Once: Current Set Point  Photodiode Current  Laser Voltage

GROUND LOOPS:ELIMINATED.
YOUR LASER IS PROTECTED.
A ground loop can destroy
your laser in an instant.
Every input and control
circuit on the LaserSource iselectrically isolated. Offset
voltages, ground connections,and AC noise will never act
on your system.
No other laser driver on themarket has this capability.
