“…Tkachuk et al [10] reported a spectral-luminescence investigation of Nd:LSO more than two decades ago, but until very recently the CW laser performance of Nd:LSO was not demonstrated [11]. Soon after, Cong et al [12] performed passively mode-locking laser operations of Nd:LSO crystal with a semiconductor saturable absorption mirror, and achieved 12.3 ps mode-locked pulse with 148.3 MHz repetition rate. A certain structural disorder due to the two different occupation sites with low symmetry for Nd 3+ ion in LSO crystal broadens the absorption and emission bands [10,11], which are favorable for diode pumping and ultrashort pulse laser generation.…”

“…The fluorescence lifetime of Nd:LSO crystal is measured to be 220-230 µs, which is similar to that of Nd:YAG crystal, but much longer than for Nd:YVO 4 crystal (110 µs). Its small emission cross-section led to high CW and mode-locking thresholds [11,12], but is favorable for Q-switching operation because the emission cross-section and fluorescence lifetime determine the energy storage ability. For the 4 F 3/2 → 4 I 13/2 transition, Nd:LSO has an emission peak at 1357 nm, which has promising applications in laser-based metrology, laser Doppler velocimeter [13], and distributed fiber sensor [14], etc.…”

With a fiber coupled laser diode array as the pump source, Nd-doped Lu 2 SiO 5 (Nd:LSO) crystal lasers at 4 F 3/2 → 4 I 11/2 and 4 F 3/2 → 4 I 13/2 transitions were demonstrated. The active Q-switched dual-wavelength lasers at about 1.08 µm, as well as continuous-wave (CW) and active Q-switched lasers at 1357 nm are reported for the first time, to the best of our knowledge. Considering the small emission cross-sections and long fluorescence lifetime, this material possesses large energy storage ability and excellent Q-switched properties. The special emission wavelength at 1357 nm will have promising applications to be used in many fields, such as THz generation, pumping of Cr 3+ :LiSAF, repumping of strontium optical clock, laser Doppler velocimeter and distributed fiber sensor.

A combined generalized spectroscopic ellipsometry measurement and density functional theory calculation analysis is performed to obtain the complete set of infrared active phonon modes in Lu2SiO5 with monoclinic crystal structure. Two different crystals, each cut perpendicular to a different crystal axis are investigated. Ellipsometry measurements from 40 -1200 cm −1 are used to determine the frequency dependent dielectric function tensor elements. The eigendielectric displacement vector summation approach and eigendielectric displacement loss vector summation approach both augmented with anharmonic lattice broadening parameters proposed recently for low-symmetry crystal structures [A. Mock et al., Phys. Rev. B 95, 165202 (2017)] are applied for our ellipsometry data analysis. All measured and model calculated dielectric function tensor and inverse dielectric function tensor elements match excellently. 23 Au symmetry and 22 Bu symmetry infrared active transverse and longitudinal optical modes are found. We also determine the directional limiting modes and the order of the phonon modes within the monoclinic plane. Results from density functional theory and ellipsometry measurements are compared and nearly perfect agreement is observed. We further compare our results to those obtained recently for the monoclinic crystal Y2SiO5, which is isostructural to Lu2SiO5 [A. Mock et al., Phys. Rev. B 97, 165203 (2018)]. We find that the lattice mode behavior of monoclinic Lu2SiO5 is qualitatively identical with Y2SiO5, and differs only quantitatively. We anticipate that members of the isostructural group of monoclinic symmetry oxyorthosilicates such as Dy2SiO5 or Yb2SiO5 will likely behave very similar in their phonon mode properties as reported here for Lu2SiO5.

“…There used to be many ways to realize mode locked laser including additive pulse mode locked (APM), Kerr lens mode locked, phaseself adjust mode locking (PSM), quadratic polarization switching mode locked (QPS), and so on. Since the invention of semi conductor saturable absorber mirror (SESAM) in 1992 [2], it has became to be a popular method to obtain mode locked laser with pulse width of picosec onds due to its simple structure, better stability and reliability [3][4][5][6].…”
