“…The rareearth scandates were previously considered as possible laser crystals. 8 The lattice parameters of several rare-earth scandates are listed in Table I. The rare-earth scandates are all orthorhombic at room temperature and isostructural with GdFeO 3 ͑and NdGaO 3 , SrRuO 3 , etc.͒.…”

“…The observed values of the refractive index of the substrate are in accordance with prior work. 8 If we assume that the scattered light intensity is proportional to the total light intensity inside the waveguide, the optical losses in the waveguide can be determined. This assumption is correct for homogenous waveguides, which the planar BaTiO 3 films appear to be from the structural data.…”

We have prepared 1-m-thick epitaxial BaTiO 3 thin films on GdScO 3 (110) using pulsed laser deposition. The structural perfection of the films was revealed by a rocking curve width of ⌬ϭ0.13°for the 002 BaTiO 3 reflection and a Rutherford backscattering spectrometry/channeling minimum yield, min , of 0.5% measured for the Ba signal behind the surface peak. High-resolution transmission electron microscopy revealed an epitaxial relationship between BaTiO 3 and GdScO 3 and a sharp interface between the substrate and the film. The refractive index of the BaTiO 3 film was n o ϭ2.329Ϯ0.002 and n e ϭ2.307Ϯ0.002 at a wavelength of 632.8 nm and n o ϭ2.248Ϯ0.002 and n e ϭ2.228Ϯ0.002 at a wavelength of 1523 nm. The optical losses were less than 2 dB/cm at a wavelength of 632.8 nm.

The spectroscopic properties and tunable laser performances of the orthorhombic perovskite Tm:GdScO3 crystal grown by the Czochralski method are comparatively studied for polarization along different crystallographic axes. The polarized emission spectrum of Tm:GdScO3 along the b-axis exhibits, to the best of our knowledge, the broadest bandwidth among all the single Tm3+-doped bulk gain media, indicating the strong inhomogeneous line broadening of Tm3+ ions in GdScO3 and thus leads to a broad and smooth gain spectrum. Tunable laser operation with a tuning range as broad as 321 nm from 1824 nm to 2145 nm is achieved, which indicates its potential for few-optical-cycle pulse generation in the 2-µm spectral range.

“…Researchers are still exploring the better host material [6][7][8]. Orthorhombic perovskite gadolinium scandate (Tm:GdScO 3 ) crystal belongs to the orthorhombic system with perovskite structure [9,10]. The lifetime was shorter than Tm:YAG, Tm:YAP and Tm:YLF, which made Tm:GdScO 3 crystal limited in big energy lasers.…”

The continuous wave laser characteristics of a Tm:GdScO3 laser were researched in this work. Under the absorbed pump power of 19.11 W, a maximum output power of 4.41 W was obtained at 1978 nm, corresponding to the slope efficiency of 28.25%. With a quartz birefringent filter (BF), a broad wavelength tunable range from 1845 nm to 2006 nm was obtained, for the first time. Then, a long-pass filter was used to replace the quartz BF. A maximum output power of 3.21 W was obtained at 2002 nm, with the slope efficiency of 21.98%. The beam quality factors M 2 for horizontal and vertical directions were 1.14 and 1.11, respectively.
