## Description
NPL and the University of Glasgow will work together to establish a service for Burn-in and Life-testing of semiconductor laser diodes in high-volume for manufacturers and suppliers of laser diodes.
The requirements for such a system are as follows:
Essential:
•	TO46, TO3, TO5, TO8, TO9 package compatibility in volumes up to 200 per month for burn-in and 100 devices for life-test per month
•	Life-test duration > 10,000 hours
•	Burn in / Life-test temperature from Ambient to 150degC with independent heaters in each module  
•	Maximum bias up to 1A on TO3 and TO8 package, and Chip-on-carrier (CoC)
•	Bar test – Typical bar with dimensions 30 mm long and up to 10 mm wide, with 100 devices across.  All the devices on the bar will require burn-in. At least 10 devices on each bar will need life-test.
•	Optical detector to monitor light output of each device under test
•	Wavelength range from 400 nm – 1600 nm
•	Temperature sensor at each device for close monitoring
•	Independent current drive for each device
•	Adaptable/re-configurable bar-test, CoC layout and # of pins on TO-packages for future “non-standard” testing requests
•	Low noise, highly stable current driver for each device (<0.1mA RMS noise)
•	Stable temperature during life-test (no variation > 1degC)
•	Remote access to monitor and control system software
