报告摘要：

The mid-infrared (mid-IR) 3-5 μm region is located in one of the two atmospheric transparent windows (the other is from 8 to 13 μm) where the Earth’s atmosphere is with relatively low transmission. Therefore it becomes an important area using remote laser sensing for the atmospheric monitoring, security and a range of industrial and military applications, such as early disease diagnosis, detecting remote explosives, countermeasures against heat-seeking missiles and covert communication systems. Glass is a non-crystalline amorphous solid, as an important material it has been well developed for a widespread range of optical devices due to its high transmission and excellent machinability. During the past few decades, most familiar, and historically the oldest glass is silicate glass, namely based on the chemical compound silica, such as silicon dioxide, or quartz glass, because of its low transmission loss in visible to near-infrared wavelength regions. However, silica glass has a reasonable high transmission loss in the mid-infrared range. Therefore a compound glass with high transparence in 3-5 µm is required to meet the demand of the host material of 3-5 µm mid-IR optical devices. The position of the IR absorption edge, i.e., the infrared longwave transmission limit, of an optical glass is intrinsically limited by the multiphonon absorption edge of the glass. So far, a range of compound glasses have been reported, such as germinate glass, fluoride glass, chalcogenide glass and so on. Compared with the traditional silica glass, compound glass is more suitable for optical gain matrix due to its lower melting temperature and higher solubility of rare-earth ions. Moreover, compound glass can be applied in mid-IR wavelength range because the phonon energies and multi-phonon relaxation rates in compound glass are much lower than that in silica glass. This talk will highlight some of the latest exciting progress in the field of compound glasses, microresonator based photonic devices and integrated photonic devices developed at the Advanced Laser Lab of the Harbin Engineering Univ. Examples of state-of-the-art compound glass based photonic components for novel near-, mid-IR and up-conversion lasing applications will be presented also in this talk.
