Encyclopedia > Janus laser
The Janus laser as it appeared in 1975.

The Janus laser was a (then considered high power) two beam infrared neodymium doped silica glass laser built at Lawrence Livermore National Laboratory in 1974 for the study of inertial confinement fusion. Janus was built using about 100 pounds of Nd:glass laser material. Initially, Janus was only capable of producing laser pulses of about 10 joules of energy. Nowadays, lasers such as the "Boericke Pulsar" have beams of up to 10000 joules. For other uses, see Infrared (disambiguation). ...
