laser applications in engineering

To ensure our journal standards remain high, we have invited top Editors from our renowned, reputable journals onto the board. Publications in Journal of Laser Applications (JLA) cover a broad range of topics from fundamental and applied research and development to industrial applications. In the mid-20th century, laser technology came out.Through the continuous efforts of generations of scientists and technicians, laser technology has been developed and perfected.From the initial principle technology development stage to the practical application field.In the 21st century, laser technology, especially laser processing technology applied in the field of the industry has been popularized and achieved considerable economic and social effects.It has played an active role in the development of natural science and technology and the progress of the social economy.Laser processing technology (FIG.

It has various unique properties such as coherence, monochromacity, directionality, and high intensity. (8) Easy to weld in high-speed and automatically, or controlled by digital or computer.

It can realize spot welding, butt welding, stack welding, sealing welding and so on. The different types of lasers are listed in Table 13-2 together with some pertinent characteristics. In more recent times, semiconductor diode lasers, operating in the 700–900 nm range, have become widely used.

In material processing, lasers with average optical power above 1 kilowatt are used mainly for industrial materials processing applications.

The laser beams are scanned horizontally under the control of a computer to form the desired images on the plates.Dry plates contain three layers, a top layer that repels ink, a middle layer that absorbs light, and a base layer that accepts ink.

Additional laser microscopy techniques include harmonic microscopy, four-wave mixing microscopyDefensive countermeasure applications can range from compact, low power Some weapons simply use a laser to disorient a person. The laser beam projector employs a rotating head with a mirror for sweeping the laser beam about a vertical axis. As in nonlaser systems, an operator at a keyboard enters in a character. At present, laser annealing of ion implantation is more expensive than furnace annealing. Communication systems: A communication system is designed to transmit and receive information using light beams like fibers.

. Historically, helium–neon lasers and air-cooled argon lasers operating at 488 nm have been employed.

. Application of Lasers in Highway Engineering.

The simplest case is that of a two-element spherical lens (doublet). Multiple locations can be measured from a single instrument position. The ability of laser-based systems to eliminate intermediate steps and to expose a printing plate ready for press, directly from computer input, is an important advance for the printing industry. (2) After confirm the single channel welding parameters of 32mm plate thick are qualified, which can reduce the time required for thick plate welding and even eliminate the use of filler metal. Cookies are used by this site.

The laser oscillator output can be formed when the positive feedback loop is added in due course.The output is not visible light, which causes severe damage to the retina and skin.

It also has higher environmental requirements (less dust).The machine requires isolation from the earthquake focus and ensure that the laser is in dry and constant temperature.Fiber laser light path is simple with not high environmental requirements (high tolerance for dust, vibrate, shock, temperature and humidity).The fiber laser is faster when cutting thin plate, and the CO2 laser is stronger when cutting thick plate.The CO2 laser can not cut high reflective metal plates.

This will increase the throughput and should remove existing restrictions on the time that it takes to fabricate an entire integrated circuit by direct write processing.
