概要

The ring length control of harmonically mode-locked Er-doped fiber ring lasers was improved to tolerate large and abrupt ambient temperature changes. By speeding up the control loop response, and also by isolating Er-doped fibers from abrupt temperature changes, a ring length change as large as 3.8 μm/sec could be compensated, and stable mode-locked operations were obtained. Also the lasing characteristics under stable operation, especially the dependence on the lasing wavelength, were investigated. The output pulses were transform-limited Gaussian in most cases, but pulse trains of shorter pulse width with double-peak spectra were observed under certain conditions.
