Laser and Amplifier Module

Our laser and amplifier module generates a laser light for the optical probes, receives the light back from the probe, and converts the light to an analog voltage.

This module is controlled via command line functions through a DB9 connector in the back of the unit.  Controls allow the user to modify the laser power, the gain of each detector (which can be set to auto-gain or to a fixed gain), and switch between AC and DC coupling.

This module has two optical-to-electrical conversion circuits, and either one or two laser circuits.

Voltage output is -5V to +5V via BNC connectors.



Several modules are available with various lasers, detectors, and connectors.  Below are the main parameters:

Available lasers:

Description Power Wavelength Class Comments
Single Mode Red 60 mW 660 nm 3B 1 or 2 lasers per module
Low Power Red 100 mW 635 nm 3B 1 or 2 lasers per module
High Power Red 300 mW 635 nm 3B 1 or 2 lasers per module
High Power Blue 400 mW 450 nm 3B 1 laser per module only


Available optical connectors:

  • ST (bayonet type), or
  • FC (screw type)

Other connectors could be wired upon request.

Available amplifier gain:

  • Regular gain range: 20 to 1,120
  • High gain range: 160 to 8,960


Standalone or Packaged

This module can be used either as a standalone unit or packaged in a Sensor Interface Unit.

As a standalone unit, the laser and amplifier module requires a 12V power supply.

Up to 8 modules can be packaged in a Sensor Interface Unit (SIU).  When packaged in an SIU, the settings of each module can be controlled in a web browser via an Ethernet connection.
