NONRING TRAVELING-WAVE LASER

A travelling-wave laser with a linear cavity configuration was propose d and constructed. The travelling-wave operation was ensured by the or thogonality of the polarisation states of the counterpropagating waves in the active medium. A fibre variant was used to achieve lasing in t he range 1.559-1.564 mu m wavelength tuning was performed by a fibre p olarisation controller. The measured lasing linewidth was less than 15 MHz and the output power was up to 18 mW.
