Title:
自己起動型受動モードロック８の字ファイバレーザ
Document Type and Number:
Japanese Patent JP7009412
Kind Code:
B2
Abstract:
A self-starting, passively modelocked figure-8 fiber laser is specifically configured to self-start into a low noise mode by controlling one or more operating parameters of the laser including, but not limited to, the coupling ratio between the uni-directional fiber loop and the bi-directional mirror loop, the accumulated dispersion within the figure-8 structure, and the amount of power present in the laser cavity. A self-starting passive modelocked figure-8 laser may also be made to self-start by initially increasing the pump current above its lasing threshold. Including a band-pass filter in the uni-directional loop has been found to ensure that the laser will enter a low noise lasing mode.
