Geola, short for General Optics Laboratory, is a small corporate group consisting of four companies based in the UK and in Lithuania. We are experts in pulsed laser photonics and holography. Since 1992 we have been developing state-of-the-art pulsed laser systems and technology for applications principally in the field of analogue and digital holography. However, many of our laser systems have also found applications in fields such as Nuclear Fusion Research, Spectroscopy, PIV, HPIV, interferometry and others.
