Appeal No. 2005-0616 Page 6
Application No. 09/661,653
The claimed subject matter
Claims 1 and 9, the independent claims on appeal, read as follows:
1. A laser, comprising:
a laser cavity having a first lasing chamber,
a second lasing chamber,
trivalent titanium ions dissolved in a liquid host within said first lasing
chamber,
trivalent titanium ions dissolved in a liquid host within said second lasing
chamber,
a first semiconductor pumping device operatively connected to said first
lasing chamber for optically exciting said trivalent titanium ions dissolved in said
liquid host within said first lasing chamber, said first semiconductor pumping
device comprising at least one semiconductor diode for optically exciting said
trivalent titanium ions dissolved in said liquid host within said first lasing chamber,
a second semiconductor pumping device operatively connected to said
second lasing chamber for optically exciting said trivalent titanium ions dissolved
in said liquid host within said second lasing chamber, said second semiconductor
pumping device comprising at least one semiconductor diode for opdcally
exciting said trivalent titanium ions dissolved in said liquid host within said lasing
second chamber,
a closed loop circulation system for circulating said trivalent titanium ions
dissolved in a liquid host through said first lasing chamber in a first linear
direction into said closed loop circulation system and into said second lasing
chamber and through said second lasing chamber in a second linear direcdon
into said closed loop circulation system and back into said first lasing chamber,
said second linear direction being opposite to said first linear direction, said
closed loop circulation system comprising
a first portion for circulating said trivalent titanium ions dissolved in a liquid
host into and out of said first lasing chamber in said first linear direction and
a second portion for circulating said trivalent titanium ions dissolved in a
liquid host into and out of said second lasing chamber in said second direction
that is opposite to said first linear direction.
9. A laser system, comprising:
an optical cavity having
a first lasing chamber and
a second lasing chamber,
