Abstract
The structure and the performance of super high power semiconductor lasers are reviewed. In 1987 1W laser which had a single broad area stripe with a 200μm width was introduced for applications such as solid-state laser pumping, medical instrument and machnning in industry. Since then, especially for solid-state laser pumping, various packages have been designed. For instance the package with a built-in TE cooler is used to raise pumping efficiency and the fiber module is used for mainely side pumping of laser rods. Alsopossibilities in getting much higher optical power have been pursued. One method is the broadening of stripe and the other is array; these methods respectively enabled the stable 3W and 10W laser.
