Modular microchannel cooled heatsinks for high average power laser diode arrays
Raymond J. Beach,William J. Benett,Barry L. Freitas,D. Mundinger,Brian J. Comaskey,Richard W. Solarz,Mark A. Emanuel +6 more
TL;DR: In this paper, an efficient and low thermal impedance laser diode array heatsink is presented for high duty factor or CW operation of fully filled diode arrays made possible at high average power.
Journal ArticleDOI
