“Using present commercial diode laser array technology, it may be possible to generate more than 25 W of average power per square centimeter or 100 mJ of pulsed energy. A desirable feature of high power microchip laser arrays is that the cost of development is primarily the cost of demonstrating a single array. Power scaling is obtained by combining several arrays. Thus, microchip laser array technology represents a new way to design and manufacture laser systems. Future microchip laser materials will include diode laser pumped vertical cavity semiconductor lasers.”
