The article discusses a study at the Japan Advanced Institute of Science & Technology & Delft University of Technology in the Netherlands, published in a 2015 issue of the journal "Applied Physics Letters," regarding transformation of cyclopentasilane inks into polycrystalline silicon using lasers.

The article reports that Polytec Inc. has released the new LSV-300 laser surface velocimeter for non-contact, online measurement, inspection and control of velocity and length in continuous process industries such as steel, metals, paper, plastic, glass and building materials. Designed to be easy to install, set up and integrate into control systems, these instruments are a valuable step to reducing scrap, increasing uptime and improving material throughput, according to the company. The LSV directly replaces traditional, high-maintenance, contact measurement techniques with accurate, low-maintenance, next-generation non-contact laser technology.

The article presents information on optical switches that increases the reliability of the photocopier. Miniature electromechanical switches are commonly used in photocopiers as sensors in the paper transport and optical subassemblies. The problem faced in photocopier is that the dust and toner particles block the switch contacts, rendering the machine unusable. Recent advances in electronics manufacturing techniques make use of optical switches or photomicrosensors instead of mechanical switches. Optical switches makes use of light to detect the presence or absence of an object. They have no moving parts to fail or jam.

The article offers information on various papers related to Light Amplification by Stimulated Emission of Radiation (LASER) theories developed by scientists including Albert Einstein and Arthur Schawlow, on the occasion of the 50th anniversary of LASERS.

This article focuses on laser-engraved plastic label introduced by Electrox Industrial Lasers. Pre-printed labels work just fine for many applications. Other situations may call for a custom label generated on the spot. Paper works, but a durable, plastic label might be just the thing. Under computer control, an engraving laser burns through the first layer, exposing the contrasting color of the second. Engraving an all-text label requires about 10 seconds, large engraved areas or logos may need 30 seconds.

Focuses on the scientific paper about laser technology printed by Lucent Technologies in honor of the 40th anniversary of the invention of laser. Basic principles of the laser; Developments in the scientific research with lasers.
