Product information "Newport Laser Diode Control"

laser diode's output is dependent on its injection current and temperature. Therefore, tightly controlling these parameters using laser diode current and temperature controllers is critical for extracting important operational parameters. Newport continually develops its precision measurement and control technology to offer a full line of innovative laser diode control instruments, test systems and accessories. Laser diode drivers are used to precisely control a laser diode’s optical output while protecting the laser diode from over-current conditions. Laser diode controllers have an integrated precision laser diode driver and high stability temperature controller. Multiple levels of laser diode protection are built into each instrument. Thermoelectric temperature controllers are used to control a thermoelectric cooler (TEC) that is typically integrated into a laser diode's package or part of a temperature controlled mounting plate.

Newport’s CW laser diode drivers are used to precisely control a laser diode’s optical output while protecting the laser diode from over current conditions. Multiple levels of laser diode protection are included in the design to protect against overcurrent conditions. Features include adjustable current limits, redundant hardware current limits, voltage limit (some models), slow start circuitry, output shorting relays and transient protection:

  • Low Cost 200 mA Laser Diode Drivers
  • Precision Laser Diode Drivers with GPIB
  • High Power Laser Diode Drivers
  • Low Noise Battery Powered 500 mA Laser Diode Drivers
  • Laser Diode Driver Cards

Newport’s pulsed laser diode drivers allow for the modulation of a laser diode using by varying the laser drive current:

  • 500 mA Pulsed Laser Diode Drivers
  • 3 Amp Pulsed Laser Diode Drivers
  • 5 Amp Pulsed Laser Diode Drivers
  • High Power Laser Diode Drivers

Newport’s laser diode controllers have an integrated precision laser diode driver and high stability temperature controller. Multiple levels of laser diode protection are built into each instrument including isolated power supplies, slow start, adjustable current limit and compliance voltage, intermittent contact protection, and output shorting relays:

  • Laser Diode Controller, LDC-37X6
  • Laser Diode Controller Cards

Thermoelectric temperature controllers are used to control a thermoelectric cooler (TEC) that is typically integrated into a laser diode's package or part of a temperature-controlled mounting plate. Newport’s range of laser diode temperature controllers may also be used to control other optical electric devices in research and development or manufacturing test and feature either an easy to set up hybrid P-I control loop or a full PID control loop. For PID control loops, an autotune method is available to reduce time to configure the temperature controller for your application:

  • ±4 A Thermoelectric Temperature Controllers
  • ±4 A and ±5 A USB/GPIB Thermoelectric Temperature Controllers
  • ±5 A and ±10 A RS232/GPIB Thermoelectric Temperature Controllers
  • ±14 A Thermoelectric Temperature Controllers
  • TEC Temperature Controller Cards

Newport’s modular laser diode controllers offer up to 16 channels of laser diode control with the flexibility of choosing laser diode driver, TEC temperature control, or laser diode controller module options that suit your needs. Everything is housed in a space saving, rack mountable instrument for simultaneous control of both current and temperature in one mainframe. Multiple levels of laser diode protection include adjustable current limits, redundant hardware current limits, voltage limit (some models), slow start circuitry, output shorting relays, and transient protection. An independent power supply powers each channel, providing protection and stability for the laser diode. Remote communication through an IEEE/GPIB interface simplifies testing and control of multiple devices:

  • Multi-Channel Modular Laser Diode Controllers
  • Laser Diode Driver Cards
  • TEC Temperature Controller Cards
  • Laser Diode Controller Cards
