Abstract
A laser having a gain medium disposed in a resonant cavity having a pair of end reflectors. One of such reflectors has a reflectivity lower than the reflectivity of the other one of the reflectors. The reflectors are arranged to provide a single ended output for the cavity through the one of the reflectors having the lower reflectivity. A saturable absorber is formed on the one of the reflectors having the lower reflectivity. With such an arrangement, fabrication of the saturable absorber on the single ended output coupler is greatly simplified. The gain medium is a doped fiber and the saturable absorber formed on the one of the reflectors having the lower reflectivity is affixed to an end of the doped fiber gain medium. With such an arrangement, a highly efficient, relatively low cost, mode locked laser is provided.
