近红外激光器 meaning in Chinese

near infrared laser

With the rapid development of optical fiber communication technology , low - cost and high quality near infrared laser and light emitted diode working at room temperature become widely available . the emit wavelength from these light resource is not only consistent with the three low - decay windows of fiber optics , but also with many wide - frequency or recombination absorption spectrum of environmental and industrial gases
光纤通信技术的发展使相对低价、工作于常温、高质量的近红外激光器和发光二极管可广泛获得,这些发光光源的发射波长与光纤的三个低损耗窗口相一致,也与许多环境和工业气体的泛频或复合吸收谱线相一致。
