Nanosecond to millisecond pulse fiber lasers Until recently, the standard nanosecond laser marking module has been able to meet most general laser marking applications. These lasers are the order of up to 50 watts of power, with the same footprint, no brightness decay. High average power and high brightness combination to maintain the high table shown ablation efficiency. In fact, these same derivatives lasers, can provide up to 500 watts of average power, pulse energy of 50 mJ. This laser is the most exciting new applications, including high-speed clearing a range of films and coatings. Microsecond to millisecond high pulse energy fiber lasers Another recent development is called quasi-continuous-wave (QCW) fiber laser. This is the concept of fiber lasers into a fiber laser pump laser flash technology, one of the last bastions of another extension: high pulse energy, low duty cycle laser processing. In this case, vertical integration, and highly cost-effective pump diode manufacturing, non-linear threshold understand and careful design, has been able to create the maximum pulse energy of 60 joules can be flexibly adjusted series of lasers. 150 watts minimum power level lasers, pump lasers with the same flash pulse length of 10 ms, with a capacity of 15 joules and 10 Hz. In the single-mode fiber can really produce this 60 Joule pulse energy? Obviously, the problem now have a definite answer, but in the real world there are few applications actually need such a pulse energy levels. Tests showed that the laser can produce not only the kind many low-power applications require large nuclear welding weld diameter, but also to cut a few millimeters thick, highly reflective material, such as aluminum and copper. Longer wavelength fiber laser emission in the spectral range from 1.5 to 2 microns erbium and thulium laser rod for some time already exist, but have not previously been used for material processing. Over the years, various modifications have high brightness fiber lasers for a variety of medical and aerospace applications. Many of these polymers having a wavelength in the absorption capacity increases; only been recently determined that the order of absorbent polymers suitable for welding transparent, thereby eliminating the need for the specific infrared absorbing agent. When using high-brightness single-mode lasers, even collimated beam can produce enough power density to form a high-quality optical transparent connection in the form of docking and welding in lap. It shows absorption polymer types in the table. Ms pulse shaping in time quasi-continuous-wave lasers latest capacity increase, is called the pulse generator (PSG) laser control package, allowing time for the vast amount of complex programming pulses. Many years ago, the time had been widely used for the flash pulse control pump lasers, and regarded as essential for some spot welding applications. To prevent the laser spot-weld the ends overlap and the emergence of pseudo-keyhole collapse associated porous loose, requiring the end of the laser pulse has a slow ramp falls, increased this demand. In this case the advantages of fiber lasers is a diode pump having a pump laser than conventional flash used flash shorter ON time. Therefore, it is possible to use a shorter pulse lengths incremental part, and more complex waveforms or.
