LASER DIODE CHARACTERIZATION

Yelo Laser Diode Characterization System

The Yelo Laser Diode Characterization system performs automated characterization of a laser device. The system will allow the operator to load a single packaged Laser device into a TEC controlled fixture mount. Each test station (LIV, Spectrum, Far Field/Beam Divergence) will then automatically align with the Laser Device in a sequential order and perform the automated tests required of each station.

SPECIFICATION

FLEXIBLE AND READY FOR ANYTHING
The system can be customized to test your laser type or range of laser types due to an interchangeable fixture design with improved flexibility.

ACCURATE TEMPERATURE CONTROL
The system can be either air or water cooled which is designed to protect your laser diode and give you more accurate test results. There is a peltier option, which allows you to accurately study the correlation between your laer diode forward current and temperature.

CURRENT DRIVE OPTIONS
Your laser diode can be driven under ACC, APC and continuous wave (CW) modes which gives you highly accurate test measurements. You can also drive your laser under Quasi Continuous Wave (QCW) mode which protects your device from overheating and becoming damaged.

NEARFIELD AND FARFIELD 
The system can make farfield and nearfield measurements to measure the optical output of your laser diode and nearfield measurements of laser bars.

ACCURATE LIV MEASUREMENTS
Accurate LIV testing from zero amps to your specific limit value. You can measure the optical output power at each current set point into an liv curve.

SPECTRUM MEASUREMENT
You can easily measure the wavelength of your laser diode and the system software will graph it automatically making for easy analysis. This is performed through an optical spectrum analyzer (OSA) or a spectrometer.

WE’LL HELP YOU EVERY STEP OF THE WAY
with us you will receive first-class support to make your testing process easy. Our experts will help you when setting up your tests. You can also receive annual on-site visits from us to keep your system fresh and productive.
