Wavelength Separation - Continuum Surelite I 10 Operation And Maintenance Manual

Continuum Surelite Laser

Wavelength separation

In most cases, only one wavelength is wanted at a time, and some means of separating the various
wavelengths emerging from the harmonics is needed. This is the role of the Surelite Separation
Packages (SSP-1, 2 & 3). Each is a set of dichroic mirrors, which isolates the desired wavelength
and steers the beam toward the appropriate output port. There are three output ports and each can
be opened or blocked by a user-removable beam dump.
• SSP-1 is needed to separate the YAG second harmonic from the fundamental after
doubling.
• SSP-2 is needed to separate either the YAG second or third harmonic from the
fundamental (or fundamental and second harmonic), after either doubling or both
doubling and tripling.
• SSP-3 is needed to separate the YAG second, third or fourth harmonic from the
fundamental and second harmonic after doubling and tripling.
In all SSP's, another option (SSP-1A, -2A or 3A) adds two mirrors for infrared output from port 3.
The SSP's also safely dispose of all unused beams into beam dumps.
