Since 1962, the advent of semiconductor lasers, especially laser marking machine, the extremely rapid development of ceramic watches laser marking machine is the most important source optical communication systems, and in the CD, VCD, DVD player, CD computer since the 1980s Many aspects of drives, laser printers, hologram, laser alignment, distance and have gained important medical applications. The semiconductor laser is a laser amplifier by injection. Although it is a necessary condition for the formation of the same laser and other lasers, it must meet the population inversion, resonance and other conditions, but it's several laser excitation mechanism and discussed different front. Its electronic transitions occur in the semiconductor material between the conduction band electrons in the valence band states and hole states, unlike atoms, molecules, ion lasers that occurs between two defined levels. Semiconductor materials have stimulated absorption, stimulated emission and spontaneous emission process. Inspired by current or light, the semiconductor valence band electrons can gain energy copper laser marking machine, the transition to the conduction band, forming a hole in the valence band, which is equivalent to the absorption process stimulated by. Also net silver shield laser laser machine, the valence band holes can also be transition from the conduction band electrons down to fill the complex. When the composite, approximately equal to the electron energy E release, which is equivalent to spontaneous emission or stimulated emission. Obviously, if in the semiconductor population inversion can be achieved, so that stimulated radiation is greater than the stimulated absorption, optical amplification can be achieved. Jun crown laser company equipment include: fiber laser marking machine, the semiconductor side pump laser marking machine, CO2 laser marking machine, end-pumped laser marking machine, metal laser cutting machine, laser welding machines, laser inkjet printer, wire laser engraving machine, laser peeling machine, laser wire stripping machine, laser coders, and other industrial laser equipment. Jun crown laser processing laser marking machine can be within a certain size range require any labeling plane, it is based on laser marking machine wavelength of 1064nm, so that it may be marking on most metals and non-metallic materials, and very good results. Different materials for the marking results bring more style, production date, barcodes, character, logo, etc., some of the material due to the different materials can also play marked color effects, such as black, gray, white, yellow and other refined products beautiful. Most laser marking machine adopts imported laser, equipped with high-speed galvanometer scanning laser marking systems and specialized software, the overall device performance more stable. Modular design, different types of laser marking machine can be divided into integrated ventilation unit and cooling unit. Higher photoelectric conversion efficiency, better beam quality, fine lines, and more, to meet the requirements of a variety of high standard.
