Solid State 193nm Laser

The Indigo-DUV is the first all solid-state, single frequency,
193 nm laser source for at-wavelength characterization of
deep UV optics and detectors.
Indigo-DUV produces >2 mW of single-frequency radiation
at 193 nm in a TEM00 spatial mode.
The near-transform-limited linewidth operation results in
a coherence length of >3 meters, enabling the precision
interferometry of lens assemblies with greater than one meter
in optical path length.
Indigo-DUV consists of a Ti:sapphire oscillator, pumped by our diode pumped
solid-state Nd:YLF Evolution laser, and a fourth harmonic frequency conversion
package.
