158-μJ pulses from a single-transverse-mode, large-mode-area erbium-doped fiber amplifier

We report the amplification of 10-100-pJ semiconductor diode pulses to an energy of 158 μJ and peak powers >100 kW in a multistage fiber amplifier chain based on a single-mode, large-mode-area erbium-doped amplifier design. To our knowledge these results represent the highest single-mode pulse energy extracted from any doped-fiber system. © 1997 Optical Society of America.

420 fs pulses from an ultrafast laser inscribed waveguide laser utilizing a carbon nanotube saturable absorber

We report the generation of 420 fs pulses of 1.56 μm light from a mode-locked ultrafast laser inscribed Er-doped waveguide laser. Passive mode-locking was achieved using a carbon nanotube saturable absorber. © 2010 Optical Society of America.

Generation of 63-nJ pulses from a fiber oscillator modelocked by nanotubes

We mode-lock a fiber oscillator with cavity length of ~1500m using nanotubes, achieving 1.55ps pulses with pulse energy up to 63nJ at 134 KHz repetition rate. © 2010 Optical Society of America.

Mode-locked and single-longitudinal-mode waveguide lasers fabricated by femtosecond laser pulses in Er:Yb-doped phosphate glass

Mode-locked and single-longitudinal-mode waveguide lasers, manufactured by femtosecond laser writing in Er-Yb-doped phosphate glasses, are presented. Transform-limited 1.6-ps pulses and a cw output power exceeding 50 mW have been obtained in the two regimes. © 2007 Optical Society of America.

1.4ps superradiant pulses from a GaN-based laser

The generation of picosecond superradiant pulses from 408nm a GaN/InGaN laser diode is demonstrated for the first time. Pulses with peak powers above 2.8W, pulse energy of 57pJ and durations of 1.4ps are generated. © 2012 OSA.

Generation of picosecond pulses with a repetition frequency of 100 GHz by a multicomponent injection laser

A mode for generating a sequence of spectrally limited pulses with a duration of 2 nsec and a repetition frequency of approximately 100 GHz in AlGaAs/GaAs by an injection heterolaser, which has amplifying and absorbing parts combined in a common resonator, is discussed.

Generation of bandwidth-limited 2 ps pulses with 100 GHz repetition rate from multisegmented injection laser

A new dynamic regime in a multisegmented AlGaAs/GaAs DH injection laser has been realised. Generation of bandwidth-limited 100 GHz repetition rate pulses has been demonstrated. This value is claimed to be the largest ever reported for an ultrashort pulse repetition frequency obtained directly from a laser.

DIRECT DETECTION OF PICOSECOND PULSES EMITTED BY AN INJECTION LASER WITH ACTIVE MODE LOCKING.

An Agat-SF linear-scan streak image-converter camera was used to record output pulses of 2. 7 psec duration generated by an injection laser with an external dispersive resonator operated in the active mode-locking regime. The duration of the pulses was determined by the reciprocal of the spectral width and the product of the duration and the spectral width was 0. 30.
