  We describe frequency stabilization of a laser at 707.202 nm wavelength using
FM spectroscopy in a hollow cathode lamp. The laser is stabilized to the
$^{88}$Sr metastable $^3\mathrm{P}_2$ to $^3\mathrm{S}_1$ optical transition.
The stabilized laser is utilized for laser-cooling and trapping of strontium
atoms. We also briefly describe the performance of a polarization spectroscopy
lock of our blue MOT laser at 461 nm derived simultaneously from the same
hollow cathode lamp.
