Ultrafast laser pulses with proper energy density and wavelength are being used for processing materials where thermal influence must be minimized, including drilling metals and cutting wafers, polymeric stents, and display glass. When amplifying picosecond and femtosecond pulses, high intensities result in nonlinear effects such as self- phase-modulation or Raman scattering, requiring sophisticated chipped-pulse-amplification in ultrafast fiber amplifiers or limiting the maximum achievable pulse energy to values of 6μJ or below. Drilling an injection nozzle hole with a high-power picosecond laser produces very sharp edges with no burr or melt and low surface roughness inside the hole, resulting in an optimum spray cloud of the fuel. An advantage of using picosecond pulsed lasers is the high cutting quality and the negligible heat-affected zone. Source

Moving enclosures for laser equipment are provided. A machine tool installation is disclosed, including (a) a laser cutting head configured to be movable in three dimensions; (b) a workpiece support configured to support a workpiece in operative relationship with the laser cutting head; (c) a skirt configured to surround the laser cutting head on three sides and intercept light that passes from the head and is reflected off of the workpiece or workpiece support; and (d) a protective cover positioned to intercept light that is reflected off of the workpiece or workpiece support and is not intercepted by the skirt. The skirt and protective cover are configured to move laterally with the laser cutting head.

A cutting machine includes a suction duct that is movable with a cutting head of the cutting machine, using a common drive. The suction duct is disposed beneath the workpiece support and coupled to the motion unit supporting the cutting head so that it moves with the motion unit while an opening of the suction duct remains positioned below the cutting head during a cutting operation. The suction duct removes cutting debris and dust, and protects underlying machine components from beam damage.

DUBLIN--(BUSINESS WIRE)--Research and Markets (http://www.researchandmarkets.com/research/q98s5p/global_and_china) has announced the addition of the "Global and Chinese Laser Processing Equipment Industry Report, 2014-2018" report to their offering. In 2014, global laser market picked up, with laser system sales hitting USD9.2 billion, a year-on-year growth rate of 6%. Over the next couple years, optical storage, military, and scientific research markets are expected to remain weak, but emerging application markets like 3D printing and sapphire cutting will fuel market growth. The global laser market is expected to grow at an CAGR of about 8% during 2015-2018. As a global processing and manufacturing center, China sees continued expansion in laser processing equipment installation. By the end of 2014, China's laser cutting complete equipment ownership approximated 20,000 units (sets), of which over 3,000 were high-power ones which are used mainly in automobile, shipping, and aerospace fields, and around 10,000 units (sets) were small and medium-power ones, finding applications in sectors such as textile & clothing, advertisement, handicraft and electronics.
