In practice, want to produce laser, just must satisfy two conditions: at first find the operation material that to realize population inversion, i.e. laser medium; Second will set up a resonator.Make the energy source (can be that resonator is outer, also can be in the resonator) of some frequencies, when laser medium repeatedly comes and goes, have enough chance de-energisations (pumping) to be in the laser medium of population inversion state at the chamber interior resonance.Only in this way, could produce laser.The photon of these stimulated emission is other atom of deexcitation again, and one becomes two, two and becomes eight of four, four changes ..., produce chain reaction, amplify like the light snowslide.Thereby produce strong laser.The Nd:YAG laser instrument is a kind of of solid crystals laser instrument, it adopts the Nd:YAG crystal bar to make laser medium, the Nd:YAG crystal is that laser medium neodymium (Nd) atom is mixed in crystal yttrium-aluminium-garnet (YAG), and the optimum content of Nd atom in YAG is about 1% of gross mass.So the full name of Nd:YAG crystal is the neodymium-doped yttrium-aluminum garnet crystal.The general benefit of Nd:YAG crystal is made into bar-shaped, and the making of this material is very difficult, and costs an arm and a leg.But because it has good optical performance, mechanical performance and thermodynamic property, so be one of best selection of superpower laser.Adopt the pumping source of xenon lamp as excitation usefulness, because it can send the light of 0.73um and 0.8um, it is the most effective encouraging the Nd atom with the light of this wavelength.Nd:YAG crystal bar and xenon lamp is placed side by side in optics cavity, and the inner surface configuration of optics cavity can all gather on the central shaft of Nd:YAG crystal bar so that guarantee the pump light that xenon lamp sends through accurate design.Can form optical resonator jointly by forward and backward speculum and laser bar.
The operation principle of present embodiment:
With reference to Fig. 3, Laser Power Devices are at first lighted the pulse xenon lamp, by Laser Power Devices to the xenon lamp pulsed discharge, form certain frequency, the light wave of certain pulsewidth, this light wave is radiated on the Nd:YAG laser crystal, excite the Nd:YAG laser crystal luminous, pass through after the resonance, sending wavelength is 1.06 μ m pulse lasers again, and this pulse laser is restrainted, reflects, focused on the back and beats on welding work pieces through expanding; Under the control of PLC, travelling table, thus finish welding.The frequency of needed pulse laser, pulsewidth, dutycycle are controlled by computer program during welding, and speed, the moving direction of workbench are then controlled by PLC, by regulating the energy of control impuls laser to the frequency of laser, the different set of pulsewidth.Laser emission heated parts surface, conduction heat by the parameters such as width, energy, peak power and frequency of control laser pulse, make the workpiece fusing to diffusion inside, form the molten bath.
The energy transfer process of Nd atom was divided into for four steps:
The first step: the Nd atom is under the excitation of 0.73 μ m and 0.8 μ m pump light at the wavelength that xenon lamp sends, the Nd atomic transition to two that is in ground state goes up in the energy level, atom the upper level lifetime here is very short, nearly 10-7 second, claims that here this energy level is an excitation state; Second step: atom does not promptly once have the transition of emission in excitation state, arrives energy level on another, and atom the upper level lifetime here is longer, is approximately 10-4 second, and this energy level is called metastable state, and atom forms population inversion here; The 3rd step: here be excited and transition when arriving down energy level when atom, will launch the photon that wavelength is 1.06 μ m, Here it is laser; The 4th step: the transition arrival ground state of emission takes place once not have here in atom again, prepares to repeat said process.
