Solid laser is a laser, laser cutting machine to choose laser relative to the other, its has a beam of light is strong, processing and the characteristics of the fine.
compared with flash, with 50% luminous efficiency of semiconductor laser laser cutting machine for solid state laser laser cutting machine is a more ideal pump sources are used. In the past ten years, gradually to batch production with high power and stability of semiconductor laser led to solid state laser from concept to the development of the whole structure. Semiconductor laser light wavelength laser cutting machine is very narrow, can adjust to and the wavelength of laser pump content Yan strictly match, so the heat generated in the solid state laser will be internal to a low, which will bring higher efficiency and beam quality of laser cutting machine laser. In addition, the service life of semiconductor laser is in commonly 10000 h above, far more than the life of the flash less than lOOOh, this makes laser as a whole becomes more reliable, and reduces the frequency of the maintenance.
the core part of typical solid laser laser cutting machine is a rod-shaped laser active medium. Rod-shaped medium is very easy to make, its important characteristics is its output laser are generally of axial symmetry. Other shapes such as rectangular slab is not very common, only when you need some special laser parameters or need to gain the material when some special specifications will be used. Industrial application of solid state laser laser cutting machine mainly adopts some rare gas lamp as light source, in the form of light pump work. But due to the flash of light emission wavelength line width is very wide, and the working substance is only absorb matching is a very narrow wavelength range of light, which means that only a small part of the pump energy is passed to the work material. In addition to efficiency, laser will produce a large amount of heat at work, and the heat can also affect the output laser beam quality and output power. Generally less than 3% of electricity can change into a laser output.
the heat load will be very strict limits of solid state laser output power and beam quality laser cutting machine. Heat is generated within the material gain, regardless of the use of coolant or a heat absorber can only cooling its edges. This will cause the pump laser working substance and temperature distribution, lead to mechanical stress. So eventually limit can provide the pump power of the laser working substance, and therefore limit stress wreck a big output power limit.
