  We developed an injection-locked Ti:sapphire laser at a wavelength of 671 nm
where the fluorescence gain of the Ti:sapphire crystal is quite low. We
obtained an output of more than 500 mW at a pump power of 10 W. The
injection-locked lasing operates at a single-frequency and unidirectionally
lasing with no intracavity optical components. The spectral property and the
stability condition for the unidirectional lasing of the injection-locked
Ti:sapphire laser are reported. The developed laser will produce the powerful
light source required for the laser cooling of lithium atoms.
