Wl. Zhang et al., OBSERVATION OF HIGH-ORDER FEMTOSECOND SOLITONS IN A SELF-MODE-LOCKED TI-SAPPHIRE LASER, Chinese Physics Letters, 14(9), 1997, pp. 667-670
The N = 3 femtosecond solitonlike pulses are observed directly in a se
lf-mode-locked Ti:sapphire laser as well as even higher-order solitonl
ike pulses for the first time. When the laser is operating in a stable
train of mode-locked pulses, the periodic pulse train appears by only
varying the intracavity dispersion. The soliton period with N = 3 cor
responds to a cavity round trip number of 164.
