Latest Patents

One of her latest patents focuses on the "Stable linewidth narrowing of a coherent comb laser." This innovative technique aims to narrow the linewidth of multiple lines of a coherent comb laser (CCL) concurrently. The process involves providing a mode-locked semiconductor CCL that outputs at least four mode-locked lines. A fraction of the power is tapped from the CCL to form a tapped beam, which is then propagated to an attenuator to produce an attenuated beam. This attenuated beam is reinserted into the laser cavity, ensuring that the reinserted beam has a power of less than 10% of the tapped beam. This method allows the CCL to operate with mode-locked lines, each having a linewidth of less than 80% of the original linewidth. By utilizing a solid waveguide and maintaining polarization in the secondary cavity, improved stability in linewidth narrowing is achieved.
