Printer Repair Laser Module (LA) The colour laser scanner is used to expose in the Raster scan digital image data on special laser paper by means of 3 Laser beams (red, green, blue). Main components of the laser tube: − glass bulb filled with gas (on the d-lab.3 Argon) − 2 mirrors (the front one is partially transparent, the rear one is opaque) − H.V. electrodes to ignite (Ionisation) the gas 1 Mirror (rear) 2 High voltage generation + electrode 3 Coupling + mirror (front) 4 Laser beam 5 Discharge dlabr147 Beam Generation The electrons are excited by the applied high voltage to jump to a higher energy level. When the gas is discharged at the change to a lower energy level, light photons are generated which hit the mirrors, are reflected there and hit other charged atoms. The atoms that are hit release several light photons and this phenomenon continues (principle of a chain reaction). If the light amplifier in the active medium exceeds the losses of the waves reflected to and fro between the mirrors, the laser starts oscillating at a wave length which is characteristic for the laser material, producing a stationary wave field between the mirrors. One of the mirrors is faintly transparent to outcouple the laser beam from the resonator. Many laser materials, like Argon, can supply the amplification for a large number of different light frequencies. The Argon ion laser of the d-lab.3 produces the blue (458 nm) and green (514 nm) beams which are available for the colour laser bundle at the coupling point. The fibre bundle guides the laser beams into the optical module where they are separated and focused in bundles by lens systems. 6.3.58 2001-01-02 /PN 9009 AGFA d-lab.3
