ABSTRACT:
Methods for operating diode lasers are provided. According to one method, the diode laser comprises a wavelength selection section, a gain section and a saturable absorber. The method comprises applying a hybrid-control signal comprising a hybrid-control DC bias to the saturable absorber, and applying a hybrid-driving signal comprising a hybrid-driving DC bias and a hybrid-driving AC bias to the gain section. The hybrid signals are selected and the diode laser is configured such that a relatively high hybrid-control DC bias corresponds to a relatively low average of the output power of the diode laser, and a relatively low hybrid-control DC bias corresponds to a relatively high average of the output power of the diode laser. The hybrid-driving DC bias is between a switch-on threshold of the diode laser and a switch-off threshold of the diode laser, and the hybrid-driving AC bias is periodic. The hybrid-driving AC bias has a peak-to-peak amplitude greater than the difference between the switch-on threshold and the switch-off threshold.
