1 医用微型激光器图1展示了一种采用普通石英光纤将波长3μm左右的激光照射在任意地方的新型激光器系统.该系统将近红外半导体激光用石英光纤导光,前端部位有与激光振荡部分集成为一体的微型团体激光器,故很容易地把目标波长激光照射在人体内.要实现该激光器,需利用半导体激光激励波长3μm.左右的激光产生振荡,并且要在光纤前端安装毫米大小的固体激光器,但是这种激光器
1 Medical Microfluidics Figure 1 shows a new type of laser system using ordinary quartz optical fiber to irradiate laser light with a wavelength of about 3μm anywhere.The system integrates the near infrared semiconductor laser with the quartz optical fiber and the front end part with the laser oscillation part as So that it is easy to irradiate the target wavelength laser in the human body.To realize the laser, a laser with a wavelength of 3 μm is excited by a semiconductor laser to generate oscillation, and a millimeter-sized solid laser is installed at the front end of the optical fiber, But this laser
