British optoelectronics expert have discussed the importance of lasers on the lives of people around the world and the potential that may still be extracted from the technology.
David Hanna, emeritus professor at University of Southampton's Optoelectronics Research Centre, told the BBC that the innovation has led to a range of applications varying from barcode scanners in supermarkets to ways of measuring the space-time of colliding black holes in the galaxy.
"People have to use their imagination about what amazing and crazy things can be done with all that capability," he said.
However, Dr Kate Lancaster from the UK's Central Laser Facility in Didcot, indicated to the BBC that treatments for cancer may be derived from advanced in lasers and the ability to "accelerate particles to high energy" in the process.
According to the expert, where radiation therapies may not use optimal energy to attack tumours, newer technology may be able to better concentrate such power and as a result offer better outcomes for patients.
Sunday is the 50th anniversary of the first ruby laser demonstration at the Hughes Research Laboratory in California.
