  We report on Bose-Einstein condensation (BEC) in a gas of strontium atoms,
using laser cooling as the only cooling mechanism. The condensate is formed
within a sample that is continuously Doppler cooled to below 1\muK on a
narrow-linewidth transition. The critical phase-space density for BEC is
reached in a central region of the sample, in which atoms are rendered
transparent for laser cooling photons. The density in this region is enhanced
by an additional dipole trap potential. Thermal equilibrium between the gas in
this central region and the surrounding laser cooled part of the cloud is
established by elastic collisions. Condensates of up to 10^5 atoms can be
repeatedly formed on a timescale of 100ms, with prospects for the generation of
a continuous atom laser.
