Laser diode arrays for high-average-power pumping of solid state lasers

Recent advances in diode pump sources include higher efficiency, higher power, longer lifetimes, wider wavelength coverage, and higher operating temperatures. In addition, advances in diode array packaging have provided for higher average power capability and an optical format that is more convenient for a variety of pump applications. We discuss advances in laser performance as well as advances in packaging technology with an emphasis on pumping of high average power solid state lasers.
