Newport 3.0 Amp Laser Diode Driver

The 5000 Series Laser Diode Drivers are advanced current sources based on the technology found in our 6000 and 8000 Series products. Full 16-bit control and characterization of your laser diodes is attainable via the IEEE-488 or RS-232C interfaces. LabVIEW drivers are included with the computer interfaces as a standard feature on all 5000 Series units.

All pertinent laser diode parameters Io, Im or Po, and Vf are simultaneously presented on the two line alphanumeric LCD display. Power in Watts is displayed when the responsivity of the monitor photodiode is programmed into the unit.

Incorrect settings are prevented during the setup mode to protect the laser diode. When power is turned off all program settings are saved. In addition, several different setups can be saved and recalled to facilitate multiple control and test requirements.

During operation the front panel inputs can be disabled by pushing the Lockout dial button located below the control knob. This prevents any inadvertent changes in the output by accidental movement of the control knob.

An internal function generator is included that is programmable from 200 Hz–300 kHz in either a sinewave or squarewave output. This provides a convenient means to generate datacom and telecom test tones for system evaluation.

External analog modulation is also included allowing you to modulate the output current using other waveforms and frequencies. Modulation is available in both the constant current (ACC) and constant power (APC) modes.

Complete laser diode protection is provided including transient detection and filtering, intermittent contact protection, independent current limit and power limit settings, multiple output shorting circuits, and a slow turn on sequence. In addition, our shielded cables protect against radiated energy from outside equipment resulting in the lowest noise output to the laser diode.
