  • Spot Laser Series
May 2006
4AD Enterprises Inc.Request Info
The compact Spot  laser series from Elforlight provides < 2 ns performance at 1064, 532, and 355 nm with TEM00 beam quality, and 25uJ/10uJ/2uJ energy levels per pulse. The lasers are suitable for interferometry, seeding laser amplifiers, ranging, micromachining, sensing, time-resolved fluorescence and other applications. The short pulses are rcreated by a unique combination of short cavity lengths and by a novel fast electro-optic q-switching technique that result in extended coherence lengths. Repetition rate is continuously variable, from single shot to 50 kHz. An add-on block provides a two-position push slide that positions filters to transmit only either 532- or 355-nm output. The residue of the other harmonics is < 2 percent of the power. A fiber-coupled output is also available via a multimode fiber launcher comprised of a focusing optic on an adjustable mount, with an SMA (SubMiniature version A) connector for fiber.

The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
The study and utilization of interference phenomena, based on the wave properties of light.
