Three lasers typical structure of a solid-state laser, ruby laser, for example, the structure right. Mixed with a small amount of chromium ions in the working substance ruby (Al203), one end of the ruby rod, polished and silver-plated a total reflection surface, and another face half silver-plated can the transmission part of the reflecting surface. Spiral flash xenon lamp as the excitation light source (pump source), the upper and lower reflector from the condenser effect. Activate the part of the Al ions in the ion chromium ion substitution crystal xenon lamp incentive light, in the ground state of the chromium ion absorption transition to the high energy level, transition to the low energy level emitted photons to produce the laser by ruby enlarge. By stimulated emission of the optical wavelength single? How to achieve a monochromatic output light? 2, gas lasers, helium-neon laser, for example. This kind of battery of green laser pointer can not be charged after being used out.
The working substance sealed in the discharge tube A 8:1 gas mixture, the excitation source is more than 3kV DC power by the C, C 'access peak reflectivity of the reflecting surface, inhibit the resonance of the other wavelengths of light to obtain the monochromatic outgoing laser. Which is decided by what? How the reflection surface reflection peak in the three dye laser plane grating: Changing the tilt angle of the grating, a wavelength of light used to adjust the grating diffraction angle diffraction greatly the formation of the light oscillation in the longitudinal axis of the resonator shoot a single wavelength laser. Continuous change of the tilt angle of the grating, continuously adjustable laser output. In short, by stimulated emission of photons with different wavelength composition. So we suggest the customer should not charge the battery of green laser pointer forcefully after the battery has been used out.
Reflecting surface can be used to determine the peak reflectivity of the grating diffraction greatly to a single wavelength of the laser output. Six laser applications at? The world's first laser was born in 1960, China developed the first laser in 1961. Laser technology with a number of disciplines combine to form more than one application of technology, such as photovoltaic technology, medical laser and photonic biology, laser processing technology, laser detection and measurement technology, laser holography, laser spectroscopy, nonlinear optics ultrafast lasers, laser chemistry, quantum optics, laser radar, laser-guided, laser isotope separation, laser controlled nuclear fusion, laser weapons. green laser pointer risks being damaged if being charged forcefully.
Laser applications include: laser processing system: laser, optical system, laser processing system of machine tools, control systems and detection systems. Laser processing, including cutting, welding, surface treatment, drilling, marking, scribing, fine-tuning and other processes. Laser welding: the thickness of automotive body panels, auto parts, lithium batteries, pacemakers, sealed relays and other sealing devices, as well as a variety is not allowed to weld contamination and deformation device. Laser cutting: automotive, computer, electrical, chassis, electronic parts, copper, metal mesh panels, steel pipes, tin-plated iron, Asia lead-plated steel plate, thin aluminum alloy, quartz glass, silicon rubber, ceramic piece, aerospace industry the use of titanium and so on. So that green laser can not be used normally.
