electromagnetic wave to generate a third coherent electromagnetic wave having a third
center wavelength in a terahertz band, the third center wavelength being longer than the
fandamental Reststrahlen wavelength.
12. Count 6 is identical to Barnes patent claim 6 and is as follows:
The method of claim 1, wherein the first and second electromagnetic waves are each
continuous-wave waves.
13. Count 7 is identical to Barnes patent claim 7 and is as follows:
The method of claim 1, wherein the first electromagnetic wave is a pulsed wave and the
second electromagnetic wave is a continuous-wave wave.
14. Count 25 is identical to Barnes patent claim 25 and is as follows:
The apparatus of claim 24, further including:
a first curved mirror in optical alignment with a first side of the nonlinear crystal, the first
side of the nonlinear crystal being a side upon which the first and second electromagnetic
waves are incident; and
a second curved mirror in optical alignment with a second side of the nonlinear crystal,
the second side of the nonlinear crystal being a side from which the third electromagnetic
wave exits the nonlinear crystal,
wherein a reflective cavity is formed between the first and second curved mirrors, the
reflective cavity including at least a portion of the nonlinear crystal, the reflective cavity
being frequency-locked to achieve double resonance of the first and second
electromagnetic waves.
15. Count 26, which is identical to Barnes patent claim 26 is as follows:
The apparatus of claim 24, wherein the first and second sources are locked together using
Pound-Drever-Hall frequency locking.
