众所周知,CTP的关键技术在光源和版材上.而版材的研制主要以所用的光源为标准。CTP所使用的激光光源的波长由长向短过渡.具体而言,这些光源是从1064nm的YAG红外激光器,到830nm的近红外激光二极管、650nm的红激光二极管.再到532nm的倍频YAG绿激光器及488nm的氩离子激光器.最后到400nm的紫激光二极管。这些激光器按照光谱范围可简单分为:红外激光光源、可见光激光光源和紫激光光源。 相似文献

Since the advent of lasers, high order multiphoton upconversion processes (HOMUPs) have been widely investigated throughout the scientific communityowing to their great fundamental significance and numerous applications in short wavelength light generation, optical imaging, and spectroscopy. Especially, upconversion pumping by means of intrinsic energy level matching of certain rare-earth (RE) ions plays a significant role in achieving short-wavelength light, due to ample availability of high power semiconductor diode lasers in the near-infrared (NIR) range. In the past decades, many efforts have been devotedto getting breakthroughs in HOMUPs, 相似文献
