This is the first time an S-band Q-Switched Fiber Laser using a MoSe2 saturable absorber has been reported.
The laser has an operational range of 1491.0–1502.0xA0;nm, making it suitable for operation in the 1-μm region.
The peak performance of the proposed laser is between 1480.0 and 1490.0xA0;nm, corresponding to the first peak gain region with the S-band.
