Quality assurance Carefully selected diode manufacturer, producing to our specifications. Rigorous testing and selection of diodes. Special cavity design and electronics ensures correct optical and electrical operating environment for the diode. This removes unwanted optical stress for the diode, which could have long term effects.

Quality assurance Highest precision specification measurement report for each laser including simulation of room temperature change. Strong destructive temperature cycling performed on each cavity to ensure long-term alignment stability. 300 hrs performance test on each laser before shipment.

Extensive testing procedures A-test Verifying specification fulfilment, By monitoring stability of wavelength and power, plus single frequency operation, in changing external/ambient temperature conditions: 20-> 30-> 20. Temperature stress cycling procdure with the diode turned off. Internal temperature of the laser is temperature is rapidly and strongly cycled up and down. B-test Verifying long term alignment immobility of components. By ensuring performance is completely unchanged, after the temperature stress cycling procedure. Comparing test A and B. Long term running, for 300 hours. End test Verifying specification fulfilment again, The same way as the A-test. Individual test report as above is shipped with each laser.
