"Fast frequency chirping... LiDAR sensor systems... Frequency conversion capabilities overcome spectral bandwidth limitations of traditional integrated semiconductor lasers... significantly relieve difficulties in developing new wavelength lasers. Narrow wavelength and fast reconfigurability, providing a "fully on-chip laser solution" to probe and manipulate atoms and ions in atomic physics, and benefit AR/VR and other applications at short wavelengths"
