摘要：
Using a simple external cavity consisting of a grating and an etalon, we demonstrate bandwidth narrowing of a high power broad-area 3-stripe laser diode array. At a drive current up to 3.6 times the threshold current, the laser diode array can always be locked. An available output of 2.3 W is obtained with the bandwidth being narrowed from 2.2 nm to no more than 0.07 nm. By tilting the etalon, the narrowed wavelength can be tuned continuously in a range of 1.6 nm. (C) 2003 Elsevier Science B.V. All rights reserved.
