Lattice Distortion-Driven Spectral Expansion in Yb-Doped GdxY0.97-xAlO3: Enabling Broadband Emission across Near-Infrared Laser Bands
High-quality Yb: GdxY0.97-xAlO3 (x=0,0.03,0.06,0.09,0.12,0.15,0.18) single crystal were successfully grown using the laser-heated pedestal growth (LHPG) method. First-principles calculations were employed to elucidate the correlation between structural evolution and luminescence properties. To the best of our knowledge, this study represents the first comprehensive investigation combining first-principles calculations with luminescence characteristics (FWHM, centroid wavelength shift, and emission intensity) for this crystal system. Our systematic analysis reveals that optimal structural modulation occurs at x=0.06, where Yb: GYAP demonstrates superior emission characteristics: a high emission cross-section (1.160 × 10-20cm2 @1006.1 nm) and broad emission bandwidth (40.912 nm @1006.1 nm). These findings establish Yb: GYAP crystals as promising gain media for 1 μm ultrafast lasers, combining both wide spectral bandwidth and high emission efficiency.
