“…In this work, a passively Q-switched 1520 nm Er:Yb:YAB pulse laser is demonstrated in a diode-endpumped plano-plano resonator, when a novel Co 2+ -doped alumina-rich Mg 0.4 Al 2.4 O 4 spinel crystal is used as the saturable absorber [9]. Co 2+ :Mg 0.4 Al 2.4 O 4 crystal has a lower growth temperature and hardness than those of the widely used Co 2+ :MgAl 2 O 4 crystal, which is favorable for crystal growth and processing [18]. At the same time, the influence of the output mirror transmission on the pulse performance of the Er:Yb:YAB micro-laser is also investigated.…”

Using an Er:Yb:YAl3(BO3)4 crystal as the gain medium and a Co2+:Mg0.4Al2.4O4 spinel crystal as the saturable absorber, an efficient passively Q-switched 1520 nm pulse laser was realized in a plano–plano cavity end-pumped by a 970 nm diode laser. At an absorbed pump power of 14.8 W and output mirror transmission of 4.6%, a 1520 nm pulse laser with 11.1 μJ energy, 16 ns duration and 27 kHz repetition rate was obtained, which resulted in about 0.7 kW output peak power. Furthermore, the influence of the output mirror transmission on the pulse energy, duration and repetition rate was also investigated.

“…On the other hand, novel alumina-rich Mg 0.4 Al 2.4 O 4 spinels with good optical quality were successfully grown by the Czochralski method [26]. Compared to stoichiometric MgAl 2 O 4 spinels, the alumina-rich spinels exhibit better optical, thermal and mechanical properties [26][27][28][29][30]. Therefore, Co 2+ -doped Mg 0.4 Al 2.4 O 4 spinels will have wide application prospects in researches of the passively Q-switched solid-state lasers.…”

Co2+‐doped Mg0.4Al2.4O4 single crystal up to ∅︁28×40 mm3 was successfully grown by the Czochralski method. By using this crystal as saturable absorber, we have demonstrated a diode‐end‐pumped passively Q‐switched Er:glass microchip laser operating at 1535 nm for the first time to the best of our knowledge. The dependences of average output power, repetition rate and pulse energy on the incident pump power were investigated. In the passive Q‐switching regime, a maximum average output power of 22.12 mW was obtained at the incident pump power of 410 mW. The narrowest pulse width, the largest pulse energy and the highest peak power were obtained to be about 3.5 ns, 4.8 μJ, and 1.37 kW, respectively.

“…Generally, there are two paths to explore the thermal and thermomechanical properties, through experimental or theoretical research. Up to now, experimental researches mainly focused on reporting the results of properties, 12–16 since that the characters of complex spinel‐type structure, including crystal and bond structures, are not easy to be revealed by experimental method. Compared to the experimental approach, the theoretical research is beneficial to revealing the composition‐dependent of thermal and thermomechanical properties deeply from the perspective of structure characters.…”

Since ceramics based on MgAlON solid solutions are promising materials as refractories, windows/armors, phosphors, etc., it is essential to explore their thermal and thermo‐mechanical properties, owing to the physical requirements on application. In this study, Mg5xAl23−5xO27+5xN5−5x were chosen for the investigation on composition‐dependent thermal and thermo‐mechanical properties by the theoretical calculations. Though the binary system with octahedral bonds contributes more to the thermal expansion coefficient of Mg5xAl23‐5xO27+5xN5‐5x, the binary system with tetrahedral bonds plays an important role in the variation of the thermal expansion coefficient. The change of heat capacity with the rise of x is mainly attributed to the variation of covalent character of Mg5xAl23−5xO27+5xN5−5x. And the thermal conductivity is mainly affected by the scattering from atoms in 8a sites. Both thermal and mechanical properties contribute to the variation of thermo‐mechanical properties of Mg5xAl23−5xO27+5xN5−5x. This study can provide guidance to designing spinel materials with desirable thermal and thermo‐mechanical properties for application.This article is protected by copyright. All rights reserved
