Tunable Argon

Melles Griot line-tunable argon-ion lasers use a Littrow prism to select a specific output wavelength. By tilting the prism, the laser can be tuned through all of the available wavelengths ranging from 454 nm to 514 nm. Depending upon the model, either eight or nine lines will be selectable. Nonetheless, only performance at 488 nm and 514 nm is guaranteed.

All systems feature both automatic power control (light regulation) and automatic current control modes that are accessible through an RS-232 interface. Output can be varied from near threshold to full power.
