Patent ID: 6931046

Claim:
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 optically 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 direction 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.
