Laser frequency control
Patent
·
OSTI ID:5234484
This patent describes a laser. It comprises means for defining a lasing cavity, a lasting medium in the cavity, exciting means for applying excitation energy to the lasing medium to produce energy oscillations within the cavity, output means for transmitting an output energy beam from the cavity at a selected frequency, power sensing means for sensing variation of the power of the output energy beam and providing a feedback signal indicative of sensed power, power supply means for supplying an excitation signal to the exciting means, and frequency control means for varying frequency of the energy oscillations. The frequency control means comprising excitation power control means responsive to the power sensing means for varying magnitude of the excitation signal to thereby vary the selected frequency.
