Paper Abstract

A custom designed compact, high brightness diode laser array stack was designed and manufactured using proprietary methods that are robust and suitable for low cost manufacturing. The diode laser stack consisted of four 10 mm-wide diode laser bars having lasing wavelength of 970 - 980 nm mounted onto high performance submounts separated by approximately 1mm. Each diode laser bar had a 50% fill factor. The cooling methodology employed used a combined passive and active scheme and not the traditional more expensive and more complicated standard microchannel coolers used for high duty cycle applications. The total combined optical power attained from the diode array stack was close to 1 kW for current levels up to 220 A, limited only by the capability of the power supply. In this paper, we summarize the performance results for this diode laser array and analyze the maximum expected optical performance as a function of operating current and pulse width and junction temperature limit.
