Bi:SiO 2 optical fibers – a possible way to understand the nature of Bi-related emitting centers
Fiber materials Fiber optics amplifiers oscillators Lasers fiber
2015/5/22
Excitation-emission properties of Bi:SiO 2 optical fibers (without other dopants) were investigated in the wavelength region 400-1600nm. Laser generation in fibers of such composition was demonstrated...
Watt-Level Bi-Doped Fiber Lasers:Breakthrough into 1300 – 1500 nm Wavelength Region
Watt-Level Bi-Doped Fiber Lasers Wavelength Region
2015/7/16
Watt-level ~20% efficiency Bi fiber lasers have been demonstrated at 1340 and 1480 nm for the first time. Optical properties of Bi-doped phosphogermanosilicate fibers depending on core composition wer...
A Novel Active MMI Bi-Stable Laser Using Cross-Gain Saturation between Fundamental and First Order Modes
Active MMI Bi-Stable Laser Cross-Gain
2015/8/4
A novel MMI-based bi-stable laser is proposed for realizing compact size. Relatively low operation current of 100mA (8mA hysteresis), and high ON/OFF optical power-ratio of 15dB were successfully achi...
All-fiber laser operating at 580 nm is realized by frequency-doubling of the Bi-doped fiber laser radiation in a periodically poled optical fiber.
