Abstract

The method of using the double-sided heat sink diodes in linear array configurations is explained. The method and efficiency of air cooling the array when arranged for diode packing of 40 diodes per centimeter is given. Data on 20 diode array operation to over 500 mW CW at 10% power efficiency is given. Also included are the initial selection criteria, burn in procedure, and final selection criteria for very long life high power array operation. Modulation data for the array is given which proves that each laser diode in the array can be current modulated in exact RF phase with the others so that the entire laser diode array is 100% amplitude modulated at frequencies to several hundred megahertz. Data is given for wavelength matching the laser diodes as in the diode pumping of Nd:YAG. Linear diode arrays with up to 100 diodes in an inch have been fabricated.
