Abstract
Section titled āAbstractāThe eye-safe range from 1.5-1.6Ī¼m has many applications such as in communications, sensing, and light detection and ranging (LIDAR) [1]. One particularly important application is wind surveying using Doppler LIDAR [2]. This requires high rep rate (>kHz) laser pulse that are narrow linewidth (MHz), short <tex xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>$(\sim 100\text{ns})$</tex> and high energy <tex xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>$(\mu \mathrm{J})$</tex> [3]. Currently this niche is filled by Er-doped fibre laser systems [4]. However, pulse energy scaling of these lasers is difficult [5]. To circumvent this, we propose a diamond master oscillator power amplifier (D-MOPA) as a final amplifier stage based on stimulated Raman scattering.
