Alexandrite (BeAl2O4:Cr3+) crystals have been growing by the Czochralski technique and continually tunable laser output with energy of 304 mJ and slope efficiency of 0.46% in the wavelength range from 735 to 786 nm has been obtained using c‐axis rods. Tunable Q‐switch pulse output and LiIO3 double‐frequency have been also obtained.
