Abstract
A number of mode-locking techniques has been demonstrated for the Ti: sapphire laser. Most studies, however, have concentrated on the steady state characteristics and relatively less attention has been paid to the pulse forming dynamics. Previously, Goodberlet et al.[1] showed that their self-starting additive-pulse mode-locked Ti:sapphire laser evolved from mode-beating fluctuations to mode-locked operation in ≈ 200µsec. For a cw passively mode-locked Ti:sapphire/HITCI laser, Ishida et al.[2] reported that the pulse train rapidly built up with a time constant of ≈ 200µsec and reached the steady state on a time scale of milliseconds to seconds. In this work, experimental results on the transient characteristics of a cw passively mode-locked Ti:sapphire/DDI laser are presented for the first time.
