Abstract :
The 1500 nm stabilised He-Ne transverse Zeeman laser (STZL) equipment is now well established, and the laser used in this equipment is specially fabricated to give a goodquality Zeeman beat frequency curve. The measurement of IF fluctuation given by two such STZLs beating with each other shows that the frequency stability of these lasers is about ±1.25 MHz for a long running time. The equipment is not complex and is suitable for coherent optical fibre communication systems.
