Progress in high power diode arrays

Recent progress in high power diode arrays include higher power output levels (>100 W/cm), higher efficiency (>50%), longer lifetimes (10/sup 11/ shots QCW, 10000 hrs CW), high temperature operation (>70/spl deg/C), and expanded wavelength coverage (670 nm to 2.0 /spl mu/m). In addition to advances in device performance, new package designs have been developed which provide for higher average power capability and optical systems have been developed to reformat the output in ways that are more convenient for many practical applications.<
