A disordered Nd:SrLaGaO4 (Nd:SLG) laser crystal was successfully grown via the Czochralski (CZ) technique. The crystal structure, refractive index, polarized absorption spectra, and stimulated emission spectra were measured. The spectroscopic properties were studied intensively with the Judd–Ofelt (J-O) theory. The maximum absorption cross sections of π- and σ-polarization at 806 nm were calculated to be 3.73 × 10−20 and 4.05 × 10−20 cm2, corresponding to FWHMs of 6.00 and 6.10 nm, respectively. The maximum emission cross sections of π- and σ-polarization at 1076 nm were 3.97 × 10−20 and 4.12 × 10−20 cm2, with FWHMs of 30.21 and 19.44 nm, respectively. The decay life of the Nd3+:4F3/2 energy level was fitted to be 0.152 ms, and the fluorescence quantum efficiency was 72.72%. The inhomogeneous broadening in spectra benefiting from the disordered structure indicates the Nd:SLG crystal is a promising gain medium for ultrafast laser and tunable laser generations in the near infrared region.

“…The structure is stable up to 1773 K, above this temperature, it dissociates into SA and SA6 (see Figure 1). Due to the incongruent melting behavior of SA6, single crystals of Nd-doped SrAl12O19 were grown using the Czochralski method in the presence of an excess of SrCO3 for laser applications [12]. Single crystals of SA2 were equally obtained using the Czochralski method [58].…”

“…The compound SrAl12O19 is a useful ingredient for the cement industry [10], as this compound has an excellent thermal conductivity of 11 W/m⋅K and high Moh's hardness of 9 [11]. Nd-or Pr-doped SrAl12O19 crystals can be used for laser applications [11,12]. Mn 2+ , Gd 3+ doped SrAl12O19 has been proposed as rewritable optical data storage compound [13].…”
