Laser Safety

LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. Stimulated emission refers to the way in which the light is generated within the laser, a process leading to a combination of characteristics which distinguish light produced by a laser from light produced by all other sources. ‘Radiation’ in the context of lasers is used as a shortening of electromagnetic radiation it should not be confused with ionising radiation produced from radioactive sources.

There are many valuable applications for lasers in engineering, manufacturing, communication technology, healthcare, medicine and research.

At the University, high powered lasers are used for cutting and welding, particle flow analysis, cavitation research, interferometry and sample preparation for mass spectrometry, to mention some.

Lower powered lasers have a very wide range of applications and are often incorporated into equipment and instruments commonly found in the office, workplace and home such as laser printers, DVD players, laser pointers, scanners, levelling and measuring devices etc.

Anyone holding, using or purchasing lasers must comply with the University's requirements as set out in Laser Risk Management and associated arrangements, instruction and guidance as provided on these pages.
