Abstract

The characteristics of monolithic ceramic Nd³⁺:YAG/Cr⁴⁺:YAG chip lasers are investigated and their fabrication technology is presented. Only CaO/MgO (without SiO₂) were used as sintering aids. The conversion of Cr³⁺ ions to Cr⁴⁺ ions was 2.19 to 2.43% in different specimens. The thickness of the transition region between Nd³⁺:YAG and Cr⁴⁺:YAG was up to 400 μm. Laser generation of pulses with an energy of up to 200 μJ and duration of up to 0.9 ns at a repetition rate of 7.5 kHz was produced.
