There are consistent frequency, phase and traffic direction, so that laser has good directionality and coherence, and, it can be very
Shorten the length of operation material well, moreover it is possible to the pattern of produced laser is adjusted by changing cavity length, so typically
Laser all has resonator, and narrow cable and wide optical fiber laser refers to that laser is exported in the form of the single longitudinal mode of chamber internal vibration, and it is special
It is that laser spectrum line width is very narrow to levy, and can reach 10-15nm, and the line width than existing narrow linewidth Distributed Feedback Laser is also narrow
Two orders of magnitude, the 5-6 order of magnitude narrower than the line width of DWDM signal optical sources in current optical communication network, narrow linewidth single longitudinal mode light
Fibre laser can ensure that laser has fabulous coherence, and its coherence length is up to more than 10,000 kilometers, narrow linewidth optical fiber
Laser has pole in superhigh precision laser radar, ship hydrophone, spacecraft launching site, intersatellite communication and fiber optic communication field
It is widely applied, but China belongs to pure importer in the field, and seen narrow linewidth laser is entirely almost external on the market
Import.
Under the conditions of the technical foundation of existing narrow linewidth laser, laser temperature regulation and control and plant maintenance on according to
So there are many weak points, analyze the temperature characterisitic of laser, show that temperature has very big shadow to the threshold current of laser
Ring, during the use of laser, be easily caused laser over-heat inside, cause many internal laser influences very big, shadow
Sound is normally used, while being assembled using internal dust is easily caused in long-time, it is difficult to clear up, easy instrument failure, laser
Costly, maintenance cost is higher for price, inconvenient maintenance.
