Double Dye

Double Dye

The Double Dye Laser combines two completely independent PrecisionScan lasers into a single housing. Each of the lasers can be pumped by different pump laser pulses and set to operate at different wavelengths. Like the PrecisonScan the Double Dye Laser is available with single or double gratings as well as a grating lift. A frequency conversion stage for each laser can be integrated into the system.

However, the dimensions of the system fit to common door openings. Both lasers of the double dye system are accessed and operated from one side.
