| Abstract: | A full-automatic wavelength controled pulsed dye laser has been developed. With the control system, dye laser oscillations
of nanosecond pulses are tuned to any wavelength in the visible or scanned in any sweep mode keeping the nearly transform-limited
bandwidth of 0.45 GHz. A mechanical tuning of the wavelength is employed, such that the motion of three wavelength selectors
is synchronized to give a smooth and precise wavelength control. The basic principle underlying the tuning scheme, various
requirements to be met in system construction, and the practical performance of automatic wavelength control are described
in this paper. |
