Abstract
A passively modelocked fiber laser includes a laser diode generating laser energy, a wavelength splitter guiding the laser energy generated at the laser diode to a cavity part, and a gaining medium for amplifying the laser energy in the cavity part. The passively modelocked fiber laser further includes a reflecting means for reflecting the laser energy along an optical axis passing through the gaining medium, an output means for outputting the laser energy generated in the cavity part, and a fiber isolator provided between the laser diode and the wavelength splitter. In the passively modelocked fiber laser, the fiber isolator is composed of an optical fiber having a curved shape and including a core for propagating the laser energy, a clad for coating the core, and an optical absorption film for coating the clad.
