Compact self-aligned external cavity lasers using volume gratings Christophe Moser
* and Frank Havermeyer Ondax, Inc. 850 E. Duarte Road, Monrovia, CA 91016, USA ABSTRACT We experimentally demonstrate a compact self-aligned external cavity 25W high power laser diode bar at 976 nm tunable over 0.5 nm…

…knowledge in 1985 [5]. Since then, others have made fixed wavelength ECLs
using VHGs for single mode and multimode high power lasers [6-9]. Although passive
alignment of an ECL with VHGs has been demonstrated [8], such an ECL is tunable only by
controlling the temperature of the VHG,…

(ECLs) that utilize spectrally filtered feedback to select the specific laser operating wavelength have been a core component in many precision systems, and can be found in many application areas ranging from Raman spectroscopy sources to fiber optic communications links. Traditional diode based ECL

…the capability of narrowing and stabilizing the wavelength of semiconductor lasers by forming an external cavity laser (ECL). The standard configuration of these ECL's is to use a collimating lens followed by the VHG to provide feedback to the resonator and lock the wavelength. In this configuration…
