Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Fiber lasers are compact compared to solid-state or gas lasers of comparable power, because the fiber can be bent and coiled, except in the case of thicker rod-type designs, to save space. They have lower cost of ownership. [1] [2] [3] Fiber lasers are reliable and exhibit high temperature and vibrational stability and extended lifetime. High ...
Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.
With a wavelength of only 1064 nanometers fiber lasers produce an extremely small spot size (up to 100 times smaller compared to the CO 2) making it ideal for cutting reflective metal material. This is one of the main advantages of Fiber compared to CO 2. Fibre laser cutter benefits include: Rapid processing times.
In fiber lasers based on double-clad fiber, an asymmetric shape improves the filling factor for laser pumping. Because of the surface tension, the shape is smoothed during the drawing process, and the shape of the resulting fiber does not reproduce the sharp edges of the preform.
ZBLAN fiber manufacturers have demonstrated significant increases in mechanical properties (>100 kpsi or 700 MPa for 125 μm fiber) and attenuation as low as 3 dB/km at 2.6 μm. ZBLAN optical fibers are used in different applications such as spectroscopy and sensing, laser power delivery and fiber lasers and amplifiers. [citation needed]
