  We herein report a simultaneous frequency stabilization of two 780-nm
external cavity diode lasers using a precision wavelength meter (WLM). The
laser lock performance is characterized by the Allan deviation measurement in
which we find $\sigma_{y}=10^{-12}$ at an averaging time of 1000 s. We also
obtain spectral profiles through a heterodyne spectroscopy, identifying the
contribution of white and flicker noises to the laser linewidth. The frequency
drift of the WLM is measured to be about 2.0(4) MHz over 36 hours. Utilizing
the two lasers as a cooling and repumping field, we demonstrate a
magneto-optical trap of $^{87}$Rb atoms near a high-finesse optical cavity. Our
laser stabilization technique operates at broad wavelength range without a
radio frequency element.
