Laser Diode Drivers

  • 6300 Series ComboSource

    The 6300 Series ComboSource Laser Diode Controller offers the best of both worlds: a high accuracy, low noise, dual-range laser driver combined with a powerful 60W precision temperature controller, coming together as our flagship product.

    The ComboSource laser driver includes the standard safety suite: a safety interlock, ESD protection, and hardware limit circuits for current and voltage. Dual range allows this instrument to operate at half-scale for improved resolution.

    In addition, the ComboSource has unique features not found on competing products including optically isolated modulation and photodiode inputs, programmable PD bias, and a constant voltage control mode.

    The ComboSource temperature controller supplies 60W of TEC control and supports all common sensor types (thermistor, RTD, AD590, and LM335), including a 4-wire RTD mode. With the same excellent stability and performance as our popular 5305 TECSource, the ComboSource supports a broad range of laser and temperature control applications.

     

    • Laser: Standard compliance voltages up to 10V
    • Laser: High accuracy, stability, and low noise
    • TEC: AutoTune for automatic PID calculation
    • TEC: Fully adjustable PID settings

    • Large, clear VFD display easily viewable with laser goggles
    • Advanced laser diode protection
    • USB / RS-232 computer interfaces
    • Command set compatibility with Newport and ILX controllers

  • 485 Series LaserPak

    The LaserPak laser diode driver is an Arroyo OEM power supply that offers the same, solid quality instrumentation our bench top units are known for, in a smaller, cost-effective solution for custom systems.

     

    The LaserPak brings the great performance and protection features found on the LaserSource into a package that is 1/3 the original size. In addition to both USB and RS-232 ports, the LaserPak replaces the standard user interface with an analog control interface not found on the LaserSource, allowing operation of the supply without the need for a computer.

    The LaserPak has all the features you expect in a laser driver, such as safety interlock, ESD protection, and hardware limit circuits for current and voltage

     

    • 2A, 4A, and 8A models standard, custom configurations available
    • Standard compliance voltages as high as 15V (call for higher voltages)
    • High stability / low noise
    • High accuracy
    • Constant current, constant power and constant voltage operating modes
    • Advanced laser diode protection
    • USB / RS-232 computer interfaces
    • Command set compatibility with Newport and ILX controllers

  • 4300 Series LaserSource

    The 4300 Series LaserSource is the ideal laser driver for medium power applications, including high power pump lasers, freespace lasers, and high power fiber-pigtailed devices and it works well with many high power LED devices. Our compact enclosure takes up very little of your workspace, and the price offers excellent value.

    Many of our customers have switched to the 4300 after years of using other products, and they have all made the same discovery: Why spend significantly more when you can get the same performance for a fraction of the price?

    The LaserSource has all the features you would expect from a laser driver, such as safety interlock, ESD protection, and hardware limit circuits for current and voltage. In addition, the LaserSource has unique features not found on competing products including optically isolated modulation and photodiode inputs, programmable PD bias, and a constant voltage control mode.

    The 4300 Series also offers an optional Quasi-CW (QCW) mode, a feature only found on far more expensive units. Using QCW mode, you can operate the device at a low duty cycle, mitigating the thermal loading on the device, and allowing you to run at higher output powers than CW operation allows. The special measurement circuitry in the 4300 even allows you to take measurements in QCW mode, which would not be possible with external triggering.

    • 2A, 4A, 8A, and 20A models available
    • Standard compliance voltages as high as 15V (call us for higher voltages)
    • High stability / low noise
    • High accuracy
    • Constant current, constant power and constant voltage operating modes
    • Large, clear VFD display easily viewable with laser goggles
    • Advanced laser diode protection
    • USB / RS-232 computer interfaces
