    • ‘The pulse energies in the solid-state laser can be higher since these lasers store energy longer and more efficiently than fiber lasers, and this higher power improves the performance of lidar and remote-sensing systems.’
    • ‘The lidar's photodiodes receive and convert the reflected laser light into electrical signals.’
    • ‘Any data that comes in 3 - D form, such as that from lidar, hyperspectral imaging, or MRI scans, can be displayed by the system.’
