G4 LaserThe G4 series lasers are compact and robust. They provide high end specifications giving a green laser output at 532nm which has superior beam quality and low noise. These single longitudinal mode systems have coherence lengths in excess of 50 metres and line widths < 0.2cm-1. These parameters enable the G4 lasers to operate very effectively in applications that require precision, such as spectroscopy, interferometry and holography.
