4308  Laser Controller 8A
The 4308 LaserSource provides up to 8A of current, with excellent noise and accuracy specs. The 4308 is an excellent choice for high power fiber pigtailed devices and other applications requiring up to 8A. Like all 4300s, the 4308 is also available with optional Quasi-CW (QCW) mode.

Simple User Interface
The 4308’s user interface is remarkably simple… so easy to use, you’ll have it up and running in no time. Unlike other instruments which rely on 7-segment LED displays and a confusing array of indicators and buttons, the 4308 instead presents the information on a high contrast VFD display in an easy-to-read format. The 4308 displays current, voltage, and photodiode current simultaneously… no need to toggle though the readings like on most instruments. Settings and error messages are in clear English, not cryptic codes and flashing status lights.

Optional Quasi-CW (QCW) Mode
The 4308 offers an optional QCW mode (see the 4308-QCW model), a feature not found in most other laser drivers in its class. Many applications require the low duty cycle, high current pulses that QCW offers to manage thermal loading on the device. With rise times of less than 20µs, and pulse widths as narrow as 100µs, the 4308-QCW offers an effective and low-cost QCW solution
