"&lt;p&gt;The EV4G green laser system is suited for marking and processing challenging materials such as silicon, colored plastics, acrylic and polymers used in the electronics, semiconductor packaging, solar and medical industries. This fiber-coupled, diode-pumped, air-cooled solid-state (DPSS) laser system produces a more than 4W laser beam (TEMoo mode) at a 532-nm wavelength.  In addition, the system is optimized for a stable performance from low- to high-power levels to handle a variety of applications and materials. &lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
