Automatic Locking of Laser Frequency to an Absorption Peak |
| Description |
This innovation is an electronic device for automatically locking the frequency of a continuous-wave laser
to an absorption peak of a gas line or Fabry-Perot cavity. The automatic capability of the device means
that the laser need not be manually adjusted to be close to the absorption peak before engaging the
frequency lock. An absorption feature within the tuning range of the laser can be detected and locked on
to. Long-term stabilization to less than 3% of the linewidth of the absorption feature has been achieved
for a diode laser locked to a gas absorption line. Flexibility is included in the design to any tunable
continuous-wave laser including diode laser and solid-state lasers. |
