This chapter provides expert coverage of the physical properties of new noncrystalline solids-tellurite glass and the latest laser applications of the material-offering insights into innovative applications for laser and sensing devices, among others. In particular, there is a focus on specialty optical fibers, supercontinuum generation and laser devices, and luminescence properties for laser applications. This chapter also addresses the fabrication and optical properties and uses of tellurite glasses in optical fibers and optical microcavities, the significance of from near infrared (NIR) to mid-infrared (MIR) emissions and the development of tellurite glass-based microcavity lasers. The important attributes of these tellurite glasses and their applications in lasers were discussed in this chapter.

“…In this section a Tm-Ho co-doped tellurite microcavity laser in the MIR region is introduced [69], with the underlying principle of operation being the transition of the 3 H6 to 3 H4 energy level in Tm 3+ ions. This was achieved using a pump with a wavelength of 808 nm, resulting in the transition from 3 H4 to 3 F4 energy level in some Tm 3+ ions, so that the energy in the Tm 3+ ions could be partially transferred to the adjacent Ho 3+ ions, prompting the transition of the ions from 5 I8 to 5 I7.…”

Abstract:In recent years, compound glass microsphere resonator devices have attracted increasing interest and have been widely used in sensing, microsphere lasers, and nonlinear optics. Compared with traditional silica resonators, compound glass microsphere resonators have many significant and attractive properties, such as high-Q factor, an ability to achieve high rare earth ion, wide infrared transmittance and low phonon energy. This review provides a summary and a critical assessment of the fabrication and the optical characterization of compound glasses and the related fabrication and applications of compound glass microsphere resonators.

“…Weak 2 µm emission intensity has remained a severe issue when employing glass hosts as gain media, where generally high pump power is required to achieve obvious laser output. [ 1,9–11 ] This severely limits their further applications in high‐performance microlaser devices. Therefore, it is urgent to exploit new‐generation gain materials used for optoelectronic applications.…”

Transparent glass ceramics (GCs) consisting of an homogeneous glass phase and a well-dispersed crystal phase are considered as ideal optical gain materials potentially applied in optoelectronic devices due to the combination of facile processability of glass and the intense crystal field of nanocrystals. Here, a heat-induced nanocrystal-in-glass method is employed to integrate the active ions Tm 3+ into Bi 2 Te 4 O 11 nanocrystals with an intense crystal field to realize an enhanced microlaser output. This strategy endows the efficient tellurate GC microcavity laser operating at ≈2 µm. Compared with the laser properties of as-prepared glass microcavities, the pump threshold (260 µW) is as low as less than a quarter and the slope efficiency (0.0296%) is 5.5 times higher. Furthermore, by carefully engineering the heat treatment temperature and duration, the crystal size and distribution can be precisely controlled. Thus, the Rayleigh scattering loss that is detrimental to quality (Q) factor is effectively suppressed and the GC microcavities with high Q factors up to 10 5 are successfully obtained. This work provides useful insight on the development of optical functional materials and expands the practical applications of GC microcavities in various optoelectronic fields.
