Stabilization of a CO 2 pump laser using external CH 3OH stark-cell modulation
Abstract
In order to stabilize the 118.8 μm CH 3OH laser output, frequency stabilization of the CW 9P(36) CO 2 laser pump is carried out using external CH 3OH Stark-cell modulation without internal frequency modulation. The CO 2 laser output power around the CH 3OH absorption center is stabilized to within ±1.0% for 60 min. The frequency stability of the CO 2 laser is estimated to be within ±1.4 MHz for 60 min, assuming the output fluctuation to be caused by this frequency fluctuation. As a result of the CO 2 pump laser stabilization, an output power stability of about ± 1.0% for 30 min is obtained for the 118.8 μm CH 3OH laser.
