英文摘要	A two-stage laser stabilization method is described to simultaneously servo two coupled laser parameters that control the wavelength of a laser, such as the laser injection current and the laser temperature, in order to simultaneously stabilize the laser frequency and output power. Two error signals are generated by passing the laser light through a frequency discriminator, such as an atomic resonance, to generate two control loops for the two coupled laser parameters. A primary control loop servos the faster laser parameter, such as the laser injection current, by direct use of the error signal. A secondary slower control loop ensures that this said error signal will remain at zero, by controlling the second laser parameter, such as the laser temperature.
