543nm Lasers

What are 543nm Lasers?

543nm green He-Ne lasers are available with both single-mode beam profiles, and with either free space or fiber coupled outputs. An He-Ne laser works by exciting Neon atoms in the gas. The optical light emitted by the laser is generated in the process when the Neon atoms decay from an excited state to an ordinary state. These laser diode packages are ideal for OEM applications. These green laser modules have an excellent beam quality and long service life. These Helium-Neon lasers are designed for multiple applications such as confocal laser scanning microscopy, spectroscopy, digital imaging, industrial measurement, alignment, testing, or medical.
