Fiber Laser Cleaning

“The Physikalisch-Technische Bundesanstalt has developed a laser with a linewidth of only 10 mHz” . Cameras based on charge-coupled devices may actually be more sensitive to laser damage than biological eyes. Class 1 is inherently safe, usually because the light is contained in an enclosure, for example in CD players. Some of the early studies were directed toward short pulses of neutrons exciting the upper isomer state in a solid so the gamma-ray transition could benefit from the line-narrowing of Mössbauer effect. In conjunction, several advantages were expected from two-stage pumping of a three-level system. It was conjectured that the nucleus of an atom, embedded in the near field of a laser-driven coherently-oscillating electron cloud would experience a larger dipole field than that of the driving laser.

Cleaning Head is portable and it operates with precise deflection and position of the laser beam. The head provides good stability with pressurized water cooling to the optics and dust proof. Simple structure of hand-held cleaning head, light weight, ergonomic design and easy to operate. High cleaning efficiency, uniform cleaning surface, no damage to substrate of components.

In most lasers this medium consists of a population of atoms which have been excited into such a state by means of an outside light source, or an electrical field which supplies energy for atoms to absorb and be transformed into their excited states. Most practical lasers contain additional elements that affect properties of the emitted light, such as the polarization, wavelength, and shape of the beam. The most common type of laser uses feedback from an optical cavity—a pair of mirrors on either end of the gain medium. Light bounces back and forth between the mirrors, passing through the gain medium and being amplified each time.

The way to overcome this problem was to charge up large capacitors which are then switched to discharge through flashlamps, producing an intense flash. Pulsed pumping is also required for three-level lasers in which the lower energy level rapidly becomes highly populated preventing further lasing until those atoms relax to the ground state. These lasers, such as the excimer laser and the copper vapor laser, can never be operated in CW mode. In a Q-switched laser, the population inversion is allowed to build up by introducing loss inside the resonator which exceeds the gain of the medium; this can also be described as a reduction of the quality factor or ‘Q’ of the cavity. This results in a short pulse incorporating that energy, and thus a high peak power. The optical bandwidth of a pulse cannot be narrower than the reciprocal of the pulse width.

We have also learned to take a step back and adjust job duties for those who have reached their capacity in a certain area. Industry is ever evolving and advancing, and we need to have the correct employees in place to ensure Chapter 2 stays at the forefront of manufacturing. Over the years, we have made some transitions in job duties and hired to fit the business needs. This does not mean that we need to fire someone or demote them — their competences are still an important asset to the company. However, it is important to recognize necessary change for the sake of the business.

Parts used for building an equipment are high in guidelines and perceived by worldwide affirming bodies. 2) precise cleaning, can achieve a precise location, the exact size of the selective cleaning. I hope you are well,my laser is operating very nicely,i have had a lot of business and it has already paid itself.Now we have some brass need to be cut,pls guide us the better parameters.

With no abrasives or secondary components involved, laser cleaning produces fewer types and lower quantities of waste products than any other cleaning process. Laser cleaning provides greater levels of control than are available for any competing process. The highly focusable and steerable laser beam can be directed precisely as desired, while sensitive and repeatable power settings deliver only the amount of energy that is called for. The range of IPG fiber lasers includes pulsed models specifically designed to produce optimum cleaning results with a minimum of heat generation. It is meticulously designed and manufactured with a compact mechanical structure and very easy to operate and move.

Outputs of individual modules can be used directly or combined to deliver high brightness outputs exceeding 100 kW, which makes fiber lasers capable of addressing a variety of industrial applications . IPG fiber lasers offer an easily automated and low maintenance solution for surface preparation and high speed cleaning for leading manufacturers. These lasers are unrivaled in their ability to strip paint or coatings, remove oil and grease in addition to modifying the texture of surfaces, such as adding roughness to increase adhesion to a material.

Graph showing the history of maximum laser pulse intensity throughout the past 40 years. Simultaneously, at Columbia University, graduate student Gordon Gould was working on a doctoral thesis about the energy levels of excited thallium. When Gould and Townes met, they spoke of radiation emission, as a general subject; afterwards, in November 1957, Gould noted his ideas for a “laser”, including using an open resonator (later an essential laser-device component). Moreover, in 1958, Prokhorov independently proposed using an open resonator, the first published appearance of this idea. Meanwhile, Schawlow and Townes had decided on an open-resonator laser design – apparently unaware of Prokhorov’s publications and Gould’s unpublished laser work. In April 1957, Japanese engineer Jun-ichi Nishizawa proposed the concept of a “semiconductor optical maser” in a patent application.

It is a professional team which specialized in production and marketing of laser machine ,cnc router machine and related technology field. However, the cost of a CW fiber laser is lower, which compensates for the disadvantage of the cleaning efficiency by increasing the average output power.

Excimer lasers typically operate at ultraviolet wavelengths with major applications including semiconductor photolithography and LASIK eye surgery. In most lasers, lasing begins with spontaneous emission into the lasing mode. This initial light is then amplified by stimulated emission in the gain medium. Stimulated emission produces light that matches the input signal in direction, wavelength, and polarization, whereas the phase of emitted light is 90 degrees in lead of the stimulating light. This, combined with the filtering effect of the optical resonator gives laser light its characteristic coherence, and may give it uniform polarization and monochromaticity, depending on the resonator’s design.
