[PDF] Laser frequency stabilization using a commercial ...

The wavemeter-based frequency stabilization scheme can be applied to a wide range of atoms and molecules for laser spectroscopy, cooling, and trapping, and provides excellent stability in single-channel operation. We present the characterization of a laser frequency stabilization scheme using a state-of-the-art wavelength meter based on solid Fizeau interferometers. For a frequency-doubled Ti ...

Frequency stabilization of DFB laser diodes at 1572 nm for ...

diode has been frequency-locked to the CO2 line center using a frequency modulation technique, suppressing its peak-to-peak frequency drifts to 0.3 MHz at 0.8 sec averaging time over 72 hours. Four online DFB laser diodes have been offset-locked to the master laser using phase locked loops, with virtually the same sub-MHz absolute accuracy.

on the light from the semiconductor laser is reduced by roughly 10 dB when the laser is optically locked to the cavity. For many applications it is important to be able to scan the laser frequency as well as to have a stable long-term frequency lock. Continuous, narrow- linewidth scans of the laser frequency can be made by
