Laser Diode Life Test
Life-tests consist of the highly accelerated ageing, under controlled conditions, of a group of lasers taken as a representative sample. Optical degradation of the laser diodes is observed and recorded by precisely measuring changes in the laser's operating characteristics during the test. Life-tests are used for vendor qualification of the laser diodes during product development and can be conducted throughout the production life of the laser.
