On Feburary 25, 2016, newest first phase publishs magazine of Optica of American optics society student of British Bath college about in the research achievement of laser of infra-red and fiber-optic gas. 3.

1 to 3.

Of 1 micron in infra-red laser is analysed in such as spectrum, the environment is monitored and explosive detects there is main use in waiting for special applying, but the laser of this domain is made not easily all the time. The scientists of Bath university put appropriate gas hollow and fiber-optic in in coming true thereby infra-red laser radiate, will medium the stability of infra-red wavelengh and fiber-optic laser, convenient, high quality, high power outputs characteristic union to rise. One of controller of this project, william Wadsorth expresses, traditional fiber-optic laser is in 2.

8 micron above keeps high power not easily, and laser of cascade of other and similar quanta also does not support 3.

The laser wavelengh under 5 micron. The much core of the data of 2 oxidation silicon that uses their research and development is hollow and fiber-optic, this problem is able to solve. Wadsorth their much core fiber-optic structure compares a series of glass canals, the reflection limitation that the light relies on these glass to be in charge of namely is transmitted in hollow fine core, is not to resemble be in common and fiber-optic transmit in vitreous fine core in that way. Be this one character, made sure this is planted fiber-optic not common and fiber-optic right in that way 2.

The absorption of wavelengh of 8 micron above problem. Hollow and fiber-optic advantage is apart from at transmitting intermediary fortunately enough long. In this example, what they used 10 meters to 11 meters is hollow and fiber-optic, it is acetylene gas among them. The investigator of Bath university people not be to think of will specific gas is filled above all fiber-optic in, there also is similar design before this. Their originality depended on increasing a paragraph of feedback fiber-optic, form reflection antrum thereby. Reflex paragraph of one part enlarge that will output light, reduced the demand to pump riverside power thereby. In this one design, the communication that used maturity uses semiconductor laser. This kind of laser is enough and practical, enough also and cheap, power is quite great also. The Chinese scholar Fei Yu of Bath group expresses, they developed consumed of a kind of benefit to come the laser wavelengh that pump riverside element produces traditional technique not easy. This kind of technology that rises gas and fiber-optic union can be used at developing to give the laser of more type. Gas is different, highest the laser of 5 micron also can use generation of this one technology to come out. CNC Milling
