Abstract
An ultra-stable laser based on frequency doubling of a distributed feedback (DFB) semiconductor laser has been built for interrogation of the 674-nm clock transition in Sr+. The DFB laser is pre-stabilized using an all-fiber interferometer that reduces the linewidth from the 1 MHz regime down to a few kHz and enables reliable locking of the laser to a 30-cm reference cavity with a finesse of 270 000 at 674 nm The laser will be used in a Sr+ single-ion clock that should reach a fractional frequency uncertainty of a few parts in 10-18.
