Bi-doped fiber lasers

Abstract

Abstract:The recent results on the new laser material -Bidoped glasses and optical fibers are reviewed. First, luminescence properties of various Bi-doped glasses are discussed. At last the results of investigations of Bi-doped fiber lasers covering a wavelength range of 1150 -1550 nm are presented.

Bismuth-doped optical fibers: a challenging active medium for near-IR lasers and optical amplifiers

“…The results of early investigations of the transmission and luminescence properties of various Bi-doped fibers are presented in a number of reviews and papers (see, for example Refs. [28][29][30][31][32].…”

“…A review of the results of the efforts to develop the early Bi-doped fiber lasers is presented in Ref. 29.…”

New Infrared Luminescence from Bi-doped Glasses

“…Optical amplification around 1.3 µm with Bi-doped multicomponent glass fiber was achieved by Seo et al , and this is useful for metro area network optical amplifiers. Laser oscillation with Bi-doped optical fiber was firstly demonstrated by Dianov's group in 2005 (Dianov, Dvoyrin et al 2005), then the possibility of Bi-doped fiber is actively developed, now the oscillation power has achieved at 15 W at 1160 nm (Bufetov & Dianov 2009). It is known that the 570 -590 nm band is very promising for ophthalmology and dermatology applications, thus the second harmonic of Bi fiber laser can be used in medical use.…”

Bismuth-doped glass microsphere lasers

“…These unique luminescent properties indicate that Bi-doped glasses are good candidates for an ultrabroadband lasing application at unconventional wavelengths and for tunable lasers. Previously, a novel fiber laser material based on Bi-doped silica glass emitting in the NIR region garnered a lot of attention [15][16][17][18][19][20][21][22]. However, the doping concentrations of Bi in silica glass are low (normally less than 0.1 mol%), the preform is fabricated at a high temperature (about 2000°C) with heavy volatility of Bi, and the emission bandwidths of the fibers are narrower than that of Bi-doped bulk glasses.…”
