Abstract
A laser that is capable of producing light from a chosen group of frequencies not adequate or available using a single gas laser is provided. The laser is capable of producing selected and well defined light wavelengths. The laser is also capable of eliminating unwanted frequencies in order to prevent such frequencies from competing with (robbing power from) the desired wavelengths. The laser constitutes a multiple gas laser. A combination of argon and krypton is used. Argon is known to produce a good blue laser beam in the area of 488 nm. Mixed with the argon is krypton. Krypton also produces a blue output at 482 nm and 476 nm. In addition, krypton produces strong outputs in red, yellow, and green wavelengths (647 nm, 568 nm, and 529 nm respectively). Accordingly, access to each of these colors is provided by the argon-krypton in the mixture. Certain light frequencies are unnecessary and undesirable. Elimination of undesirable wavelengths is accomplished primarily through the optics used. Optics are chosen which transmit unwanted wavelengths. As a result no lasing action takes place at the unwanted wavelengths.
