4304 Laser Controller 4A
The 4304 LaserSource provides up to 4A of current, with excellent noise and accuracy specs. A good choice for applications such as c-mount and TO-3 devices operating up to 4A. Like all 4300s, the 4304 is also available with optional Quasi-CW (QCW) mode.

High Compliance
The 4304 features a high 8V compliance for higher voltage applications, such as LED testing or quantum cascade lasers, as well as excellect performance with lower voltage laser diodes.

Simple User Interface
The 4304’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 4304 instead presents the information on a high contrast VFD display in an easy-to-read format. The 4304 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 4304 offers an optional QCW mode (see the 4304-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 4304-QCW offers an effective and low-cost QCW solution.
