Crystal growth and spectroscopic properties of Nd3+ -doped SrB4O7 single crystal

Single crystal of Nd3+ -doped SrB4O7 (SBO) has been successfully grown by the Czochralski method. The spectroscopic properties were investigated, and spectral parameters were calculated based on the Judd–Ofelt theory. The results suggest that the Nd:SBO crystal may have great potential as laser crystal, and through self-frequency doubling, it is expected to achieve the frequency conversion of the characteristic output of Nd3+ in the near infrared to obtain a visible laser.
