Abstract

The new laser crystals BeAl₆O₁₀:Cr³⁺ were grown, spectral-luminescence and CW laser properties were investigated and compared with those of well-known laser medium-alexandrite (BeAl₂O₄:Cr³⁺). CW laser generation on vibronic transition ⁴T₂-⁴A₂ of Cr³⁺ ions in BeAl₆O₁₀ crystals was realized in the range of 800-880 nm under Ar⁺ laser pumping. The emission cross-section of laser transition was estimated about 6×10^-20 cm². We confirmed these crystals are perspective for generation of femtosecond pulses in the near IR region under LD pumping.
