ABSTRACT:
An injection seeding laser system in which the seeded laser has a monolithic structure without any moving parts. The seeder emits light whose wavelength is swept in a radio frequency (RF) over a range that covers one or more longitudinal mode(s) of the seeded laser, which eliminates the need for active cavity length control and phase locking between the injected and output signals. The gain medium of the seeded laser is an active medium whose population is substantially inversed in response to an excitation, which can be electrical or optical. Time synchronization between the injected seeds and the triggering signal to the slave is generally not required. The present invention enables fiber MOPO that produces high power laser pulses in an efficient and cost-effective manner.
