Factors cutting laser YAG laser output power machine

laser cutting machine in the use of laser increases the injection of electrical energy, there is a certain range of the fluctuation of laser power, and thus the stability of the device is a very important goal .

Laser output power is affected by the following factors power attenuation

(1) of the lamp. Krypton lamp as consumables, efficiency in the use of lower power will slowly degrade ovshanghai companyer time, down lamp power will affect the stability of the laser power. Further, as the ordinary pure water contains a large amount of microorganisms and various ions, so that the temperature of the lamp tends to stick to the walls of these impurities, but also caused a decrease in the efficiency of lamp.

(2) the thermal deformation of the cavity mirrors. Parallel to the plane of symmetry of the mold cavity has a larger volume in the crystal, and as the power increases, resulting in thermal deformation of the cavity of the lens is changed, the transition from one stable non-cavity resonator -stable, which affects the laser output power.

(3) the mode volume of laser crystal. Proportional to the volume of the laser power and the laser crystal size of the mold, the larger the volume the greater thesmall gold mining shaker table india power in laser mode. However, with the increase of the injection of electrical energy, the thermal effects resulting crystals are serious, leading to changes in the crystal volume of the mold, the incidence of the laser output power .

More objective factors in the design of the laser is inevitable to ensure the stability of the output power of the laser, we must ensure that each of the heaters laser quickly reach steady state heat.
