Advantages of Fibre Laser Processing

Principles and Application of the Fibre Laser:

 

Fibre laser means a type of laser mixing rare earth glass fibre as the laser gain medium, the fibre laser can be developed base on the fibre optic amplifier: under the function of pump light, the fibre is flexible to form the high power density, resulting the laser energy level “population inversion” of the laser materials. When adds the regenerative circuit (forming resonant cavity) suitably, it will form the laser vibration output.   

 

The fibre laser is of wide scope of application, including laser fibre communication, laser space long distance communication, industrial ship building, car manufacturing, fibre carving, fibre marking, fibre cutting, printing roller, metal/non-metal drilling/cutting/welding (brazing, quenching, wrapping and deep welding), military affairs and national security, medical apparatus instrument, and large infrastructure, etc.

 

Advantages of the fibre laser:

 

As the symbol of the third generation of fibre laser, it is featured with the following advantages.

 

 1. Low cost on glass fibre manufacturing, perfect technology and the minimized and integrated advantages due to the flexibility of fibre.

 

2. The incoming pump light on glass fibre is not required to be strictly of phase matched like that on crystal, due to the non-uniform spread of the branches resulting from the division of glass matrix Stark brings about the wide absorption band.

 

3. The fibre materials has relative low ratio of volume to area, with fast radiation and low loss, the upper conversion efficiency is relative high and laser threshold is low. 

 

4. The output laser wavelength is more, due to the rare earth ion is abundant and rich, and its rare earth iron is of multiple kinds.

 

5. The tuneable ability: the energy level of the rare earth iron is wide, and the fluorescent line of the glass fibre is wide.

 

6. Due to the resonant cavity of the fibre laser has no optical glasses, it has free of maintenance and high stabilities, which is incomparable by the traditional laser.   

 

7. Fibre export enables the laser capable to be qualified for all kinds of multi-dimension space processing and application, simplifying the design of mechanical system.   

 

 8. Work normally in the serious working environment: it has high tolerability to the dust, vibration, punching, humidity, and temperature. 

 

9. No requirement on the thermoelectric refrigeration and water cooling, only the simply air cooling.    

 

10. Higher electronic-optic efficiency: its comprehensive electronic-optic efficiency is over 20%, saving the power consumption greatly and the operation cost.
