Ground Loops? A Thing of the Past!

Ground loops can plague instrument setups. In a

major design improvement over traditional laser drivers,

all inputs (computer interfaces, modulation, and photo-

diode) and drive output are optically and electrically

isolated from each other, creating a versatile instrument

that is unaffected by the electrical conﬁguration of your

diode or other test equipment. Even the photodiode

input is fully isolated from the laser output, ensuring

full isolation of the laser output from unwanted ground

loops and other electrical disturbances. No other driver

on the market has this capability.

Computer Interfaces Standard. Always.

While all instrument manufacturers offer some of

their drivers with computer control, it is typically only

on their more expensive units, adding hundreds of

dollars to the cost of the instrument. All LaserSources

come standard with USB and RS-232 computer

interfaces, and are command set compatible with

other manufacturers’ drivers. This command set

compatibility allows you to leverage any existing

software you may have already developed.

Analogue modulation?

Yeah, we got that, too.

All LaserSources support analog modulation via the

BNC jack on the rear of the instrument. Hardware

protection is active during modulation, protecting the

laser diode regardless of the modulation input signal.

Need to do QCW measurements?

We’ve got you covered.

All 4300 Series LaserSources can be optionally equipped

for quasi-CW (QCW) measurements, and feature both

a trigger in and trigger out BNC for synchronization with

other instruments. Analog sample-and-hold registers

capture the current, voltage, and photodiode power

at the end of the pulse, providing accurate diode

measurements. Pulses can be generated internally

by selecting pulse width, frequency, and duty cycle,

or triggered externally. To assist in timing between

instruments, the trigger in and trigger out have

independent pulse delays. Adding QCW mode does

not mean you lose CW operation: QCW-equipped

instruments retain all the capabilities of their

CW-only cousins.

No Manual? No Problem!

Unlike other instruments, the LaserSource employs

a dot-pixel character display that allows for human-

readable status, readings, and errors. No longer do

you need to get out the manual to ﬁgure out how

to set the current limit, or to understand what error

114 is; you can read it directly on the display in plain

English. This allows the user interface to be greatly

simpliﬁed and at the same time easier to use.

Current or Voltage

Don’t Match? Call Us...

While we offer several standard current ranges, many

applications require higher voltages or higher currents.

Call us to discuss your high voltage or high current

application, and we’ll see if we have a solution for you.
