Bismuth masking technique for use on injection laser diodes as means of uniformity evaluation and spontaneous control and product

摘要: 1. A METHOD OF MASKING THE LASING REGION AN INJECTION LASER DIODE WHICH COMPRISES STEP OF: (A) COATING SURFACE SAID WITH MATERIAL SUFFICIENTLY LOW ELECTRICAL CONDUCTIVITY NOT TO EFFECT PROPERTIES AND EVAPORABLE AT POWER LEVELS DO DEGRADE DIODE; (B) PULSING ENERGY LEVEL HIGH EVAPORATE MATERIAL, WHEREBY EVAPORATES ALONG DIODE.
