Efficient all-fiber bismuth-doped laser

Abstract

In the present letter the authors report on the realization of an all-fiber bismuth-doped laser with laser emission that can be chosen with corresponding fiber Bragg gratings between at least 1150 and 1225nm. In their experiments they achieved a slope efficiency of about 24% at 1200nm, which is the highest reported for this kind of laser.

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].…”

New Infrared Luminescence from Bi-doped Glasses

“…After the discovery of a new infrared luminescent bismuth center, several research groups started to study its applications, such as optical amplification (Fujimoto & Nakatsuka 2003;Ren, Wu et al 2007;Ren, Dong et al 2007;Ren, Qiao et al 2007;Seo, Lim et al 2007), waveguide inscription(Psaila, Thomson et al 2006), or laser oscillation (Dianov, Dvoyrin et al 2005;Dianov, Shubin et al 2007;Razdobreev, Bigot et al 2007;Rulkov, Ferin et al 2007;Truong, Bigot et al 2008) using Bi luminescent materials. With respects to device applications, optical fibers with Bi luminescent center in the core material are very curious.…”

Infrared luminescence and amplification properties of Bi-doped GeO2−Ga2O3−Al2O3 glasses

“…16 It is exciting that optical amplification and lasing operation were also realized at present. [17][18][19][20][21][22] Among the obtained results, an interesting phenomenon that was seldom observed in other active materials is the excitation wavelength sensitive luminescence, and the largest displacement of 200 nm was reported. 12 This special characteristic is significant since it offers the opportunity for realizing tunable and broadband lasers and amplifiers.…”
