There will be hands-on activities involving Laser Beam equipment.

In the Photonics Academy of Wales @ Bangor (PAWB) Design Laboratory, a not uncommon personal greeting is “What have you invented, today ?”. PAWB exists to encourage all students to create highly innovative new applications of Low Power Laser Beams. Photonics is the Science of the Harnessing of Light – and that is what PAWB does – PAWB seeks to encourage students to harness the Light from Low Power Laser Beams in highly innovative ways.

Light from a Laser has just four fundamental characteristics, and there are just four treatments which can be applied to a Laser beam. Hence, from within these eight significantly different Laser Beam features, PAWB seeks to face the challenge of seeking opportunitiesto create many different applications of a Low Power Laser Beam, as always is achievable, through the inherent imagination and ingenuity of any student.

In this talk, I will briefly indicate the eight different characteristics of a Laser Beam, and then focus specifically on the PAWB approach to Photonics Design, through the PAWB Technique of TriadA. An initial sequence of practical audience involvement in investigative demonstrations, will be narrowed down to focus on just two of the Laser Beam characteristics, to which the human eye does not have any sensitivity response, and which are overflowing with creative Design potential – namely Laser Beam Speckle and Laser Beam Polarization – both being produced by most unusual Laboratory mechanisms, which very few people ever have encountered – both are PAWB Photonics specialities.

All the Laser Beam equipment, present for this Presentation, will provide CUPS members with an opportunity to take some initial steps towards the design of any number of new Laser based inventions – all, perhaps, with a PAWB based encouragement to utilize Laser Light Beams for the benefit of those individuals who may be visually impaired, and who cannot actually see the Light which is providing them with some helpful benefit.
