日本滨松光电子公司研究出一种制造3μm～5μm波长量子阱结构半导体激光器的技术。因为不需要液氮和致冷器,故可用于测定地球暖化气体和大气污染气体浓度以及光通信方面。
Japan Hamamatsu Photonics has developed a 3μm ~ 5μm wavelength quantum well structure semiconductor laser technology. Because it does not require liquid nitrogen and a refrigerator, it can be used to measure the concentration of gas and atmospheric pollution gases in the Earth as well as optical communications.
