The energy of the helium-neon laser source is much less than that of of most lines of the Argon-ion laser source, making the He-Ne laser the proffered source if the compound undergoes photochemical decomposition. He-Ne would be chosen also if the sample has background fluorescence excited by the argon-ion laser. wavelength and output data and might indicate the general laser name (i.e. Argon, HeNe). Before sending the laser to surplus, the user shall place a sign on the laser indicating its optical laser medium (i.e. Nd:YAG, Dye, Argon etc). This will be a great help to the property disposal group especially if the user manual cannot be Size: KB. Positive Evans blue exudation (EBE) from the laser-irradiated dorsum skin of the ddY mouse was used as the indicator. The correlation of the irradiation times to achieve EBE with the argon laser standardised at 1 was for the Nd:YAG and for the CO 2. The possible use of these figures in the medical application of the laser is : Toshio Ohshiro.

A Brief Introduction to Argon Ion Lasers: Although the argon ion laser was not the first laser invented, it has become one of the most popular ion lasers in use today. Invented in by William Bridges at Hughes Aircraft, the argon ion laser uses, as its name implies, high purity argon gas as the lasing medium.

Argon ion lasers are powerful gas lasers, which typically generate multiple watts of optical power in a green or blue output beam with high beam quality. Multi-watt argon ion lasers can be used e.g.
