SHOW PREVIEW: SPIE PHOTONICS WEST


SHOWCASING LASER PROCESSING SCIENCE


The photonics show, SPIE Photonics West, will


cover innovations in industrial laser processing when it takes place in San Francisco, USA from 28 January to 2 February 2017. Here, we preview some of what will be on display


M


ore than 20,000 people are expected to attend SPIE Photonics West in San Francisco at the end


of January 2017. Alongside the exhibition, the show will feature 5,000 technical presentations over three strands: Bios covering biophotonics; Lase about industrial lasers; and Opto covering optoelectronics. The Lase conference will feature


research on laser manufacturing, laser materials processing, micro-nano packaging, fibre, diode and solid-state lasers, laser resonators, ultrafast processing, semiconductor lasers and LEDs, and 3D fabrication technologies. The Lase plenary session on 1


February from 10:20am to 12:30pm will have talks from Professor Dr Karsten Danzmann on gravitational wave astronomy; Dr Alberto Piqué on printing hybrid electronics by


COHERENT will present its new 120W CO2


laser direct-write processing; and Dr Hakaru Mizoguchi on the development of a 250W EUV light source for HVM lithography. Different industry events will also


take place throughout the show, including the Prism Awards recognising innovative commercial products – finalists in the industrial laser category are: Amplitude Systèmes for its ultrafast laser; Photonics Industries International for its pulse picker technology; and QD Laser for an ultrashort pulsed seeder for fibre lasers. In addition, the Startup


Challenge will give entrepreneurs the chance to pitch their new photonics business and compete for $20,000 in cash and products. There are also events organised for students, along with those for professional development. http://spie.org/conferences-and- exhibitions/photonics-west

ELEMENT SIX will showcase its Optical+ Low Absorption diamond at the show; this can be used as a low loss intra-cavity heat spreader for high power disk lasers, as well as a gain medium for Raman lasers. Raman


It is a direct diode laser product with an integrated water chiller and thermistor. The module has no moving parts, which makes the laser particularly reliable. The expected lifetime of the module is more than 10,000 hours, with its main applications being plastic material processing and accurate micro- soldering on PCBs; it is also suitable


crystals are offered in sizes up to 6 x 6 x 2mm, with larger sizes available on request. Also featured will be the company’s


Diamond PureOptics range. Drawing inspiration from the anti-reflective structure of a moth’s eye, this all-diamond solution offers improved reliability and even higher power density levels for high power CO2


systems. Element Six has replaced the


laser, the Cx-10, which is


30 per cent smaller than other lasers of the same type. Its size enables the construction of more compact laser-based systems for space constrained industrial applications. Additionally, the Cx-10 offers a combination of performance and reliability features to deliver both superior processing results and a lower total cost of ownership. These include increased throughput speeds and a shorter pulse fall time than other waveguide CO2


lasers at this power


level, which yields a smaller heat affected zone on the workpiece.

ensures process uniformity and repeatable results. The Cx-10’s reliability is enhanced through an integrated RF power supply and a modular RF board, which also facilitates field serviceability. Cx-10 lasers are intended for a range of high volume marking, cutting and engraving applications employing a

typical anti-reflective thin film coatings found on diamond optical windows 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 anti-reflective coated windows, with equivalent reflectance (less than 0.5 per cent) and transmission (above 99 per cent). www.e6.com


FRANKFURT LASER COMPANY will present the Fach-450-10WFC105, a new high power blue laser diode module with exceptionally high brightness. The module delivers more than 10W of power at 450nm- wavelength into the 105µm core fibre.

JENOPTIK will display the F-theta JENar Silverline. The high damage-threshold of the lens assured by the quartz material and optimised coating makes it ideal for use with high-powered lasers and ultrashort pulses. The F-theta Silverline lens has a


maximum telecentric angle of 4.9° and a highly homogeneous spot size distribution across the whole of the 100 x 100mm work area. This large processing area, in combination with the diffraction- limited image quality, allows for increased throughput in comparison with standard lenses available on the market. Jenoptik’s beam expanders


have also been redesigned. The first new continuously variable beam expander BEX 1x–4x has an innovative mechanical design, ensuring high reproducibility of lens settings and stability against shock and vibration. www.jenoptik.com/os
