Erbium-doped and Raman microlasers on a silicon chip fabricated by the sol–gel process [PDF]

, 2005
We report high-Q sol–gel microresonators on silicon chips, fabricated directly from a sol–gel layer deposited onto a silicon substrate. Quality factors as high as 2.5×10^7 at 1561 nm were obtained in toroidal microcavities formed of silica sol–gel ...

Chirped pulse amplification in an erbium-doped fiber oscillator/ erbium-doped fiber amplifier system [PDF]

Optics Communications, 1994
Abstract Chirped pulse amplification in erbium fibers is demonstrated. A passively mode locked erbium-doped fiber laser source provides the seed pulses for an erbium-doped fiber amplifier. The system produces femtosecond pulses at a repetition rate of 33 MHz with an energy content as high as 1.4 nJ.
