The 4300 Series LaserSource is a high-accuracy laser driver capable of supplying up to 20A for low and medium-power laser and LED applications. This laser driver offers features typically found in only more expensive units, such as overlapping laser protection systems and an optional QCW mode.

 

4300 FEATURES:

The 4300 Series LaserSource is the ideal laser driver for medium power applications, including high power pump lasers, freespace lasers, and high power fiber-pigtailed devices and it works well with many high power LED devices. Our compact enclosure takes up very little of your workspace, and the price offers excellent value.

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.

The 4300 Series also offers an optional Quasi-CW (QCW) mode, a feature only found on far more expensive units. Using QCW mode, you can operate the device at a low duty cycle, mitigating the thermal loading on the device, and allowing you to run at higher output powers than CW operation allows. The special measurement circuitry in the 4300 even allows you to take measurements in QCW mode, which would not be possible with external triggering.

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

QUASI-CONSTANT WAVE MODE (OPTIONAL)
QCW mode provides low duty cycle, high current pulses to manage thermal loading. Rise times less than 20μs. Pulse widths as narrow as 100 μs.

ANALOG MODULATION
Bandwidths up to 65 kHz.

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

SIMPLE USER INTERFACE
Easy to Read, High Contrast VFD Display with all messages and settings in plain English. View All 3 At Once:
