A recognized drawback of edge-emitting diode lasers is their high divergence and elliptical beam shape since the first diode laser was demonstrated. In this paper, we demonstrated the ultranarrow ...

Helium-neon lasers at 633 nm are still widely used in interferometers and, stabilized to iodine, serve as secondary frequency standards for the practical realisation of the meter [1]. However, the ...
