A multi-mode diode laser with an external cavity is studied experimentally and theoretically
for its application to intra-cavity spectroscopy. One facet of a typical Ga 0.89 Al 0.11 As laser …

Silicon nitride and silicon oxynitride dielectric layers were fabricated by reactive RF
sputtering from an Si target in conventional equipment. Sputtering was done using a gas …

A broadband 1.5 μm GaInAsP travelling-wave laser ampli-fier has been realised with angled
facets instead of anti-reflection coatings. The measured signal gain for the TE mode is 19dB …

The first use of an external cavity diode-laser light source in combination with a
photoacoustic detector for high-sensitivity gas detection is described. This combined system …
