SHOW PREVIEW: PHOTONICS WEST LASER TECH HEADS WEST
The photonics conference and exhibition, SPIE Photonics West, will be held in San Francisco, US from 16 to 18 February 2016. Here we preview some of the technology for industrial laser processing on display at the show
Synthetic diamond manufacturer, ELEMENT SIX, will be showcasing its Diamond PureOptics diamond optics range. The technology has been nominated for a Prism Award for photonics innovation, the winners of which will be announced at the show. Drawing inspiration from the
anti-reflective structure of a moth’s eye, this all-diamond solution offers improved reliability and higher power density levels for high power CO2
laser systems. Diamond optical windows typically
include an anti-reflective (AR) thin film coating to minimise reflection losses and maximise laser output power. However, these coatings have mechanical and thermal properties far inferior to those of diamond, leading to increased thermal and mechanical failures as optical power densities increase. Element Six replaced these thin films with a diamond structured surface designed to reduce reflection losses. Diamond PureOptics exhibits a significantly higher laser-induced damage threshold (by a factor of 10) than AR coated windows, with equivalent reflectance (less than 0.5 per cent) and transmission (more than 99 per cent). Diamond PureOptics optical
windows for 10.6µm wavelength have been designed, fabricated and field-tested and are available now for shipment.

OPHIR-SPIRICON will showcase new technologies for measuring and controlling high power laser parameters. BeamWatch is an industrial beam
monitoring system that measure focus spot shift, waist width, and M2 for high power YAG, fibre, and diode lasers without contacting the laser beam. Designed for material processing applications to 100kW and higher, BeamWatch measures focus spots down to 55µm. Two-axis viewing allows determination of roundness. Ophir’s 120K-W laser power meter is a commercial sensor for
SCANLAB will exhibit its new ExcelliScan scan head at the trade show. The scan system uses servo innovations to deliver productivity gains in industrial applications such as micro-processing. Developed to meet rigorous demands for dynamics, precision and long-term stability in continuous operation, the scan head’s mechanical design is compact and provides optimal heat removal under dynamic load. ExcelliScan uses galvo scanners with precise digital angle sensors
operation of CO2 , NIR, far IR THz
lasers, Ophir’s Pyrocam IV camera delivers 2D/3D beam profiles that show detrimental variations affecting laser performance. Instant feedback allows timely correction and real-time tuning. GigE interface is provided for high-speed applications. Pyrocam profiles beams to 25mm, with no need for reduction optics.

PRIMES will be displaying the Power Measuring Cassette, a device for making power measurements of solid-state lasers. The flexible and compact tool can
work both stand-alone and directly integrated into the protective glass slot of a laser processing head. The
and a new ScanAhead servo control. This control solution enables dynamic laser processing without the limitations of conventional servos with tracking error. The servo design achieves high speed and dynamic performance, thus delivering productivity gains. Moreover, high-speed contour marking accuracy (for example, starting off from sharp corners and curves) is significantly improved.

calorimetric measuring system covers a power range from 200W to 8,000W. Typical irradiation times range from about 100ms to 1,000ms, depending on the laser power. The product has an integrated
display and the battery is sufficient for several hundred measurements before recharging via micro-USB. An interlock connector provides additional safety against overheating.
