Laser Diode Burn-In Racks

Don't think of it as a Burn-in Rack. Think of it as a Multi-position Test Station.

The sky is the limit with our burn-in racks. We have standard models, but if you want something special, we’re up for the challenge!

  • All our racks are capable of accurate measurements of typical diode parameters and multi-step burn-in recipes.  We can even run LIV+Spectrum on our racks!
  • The newest addition to our rack family is the new small-footprint single-bay rack.  This rack will allow up to 25 KW of burn-in capacity within a standard 19" rack footprint.
  • We support all known laser diode formats and cooling methods.
  • Our burn-in racks are optimized for the application

Rack Format:

We have 3 rack formats:

  • Single-Bay (Small footprint) - Optimized to take up the minimum floor space.
  • Double-Bay - Supports many more devices than a single-bay rack
  • Multi-Bay - Similar to the double-bay racks except even more devices can be run.

Products Supported:

Our burn-in racks can be configured to support:

  • Fiber-coupled and uncoupled laser diodes
  • Passively and actively-cooled devices
  • Single emitters, bars, and stacks
  • Lensed or unlensed devices
  • CW or pulsed devices or recipes
  • High-current (>300A) and high-voltage (>80V) devices
  • A mix of all of the above

Measurements Supported:

  • Device current
  • Device voltage
  • Cooling water input & output temperature
  • Cooling water flow rate (optional)
  • Cooling water input & output pressure (optional)
  • Fiber boot temperature (optional, fiber-coupled devices only)
  • Optical output (optional)
  • Wavelength (optional)
  • Custom measurement types as specified by customer (optional)

Other Features:

  • Multi-Step Recipes: This allows a burn-in recipe to have multiple steps with varying parameters for maximum burn-in flexibility.
  • Multiple Interlocks: These protect both the devices and the rack in the event of an illegal operating condition.
  • On-The-Fly Device Dropout (optional): This allows a single device in a string of devices to be dropped out of the burn-in if the device’s critical parameters go outside the acceptable range.
  • Optical Power Interlock (optional): This quickly cuts the power supply output if the device optical power goes below a critical level.  This prevents the device from destroying itself and allows for diagnostics or rework.  It is available for both pulsed and CW operation.

We have the right solution for you.
