title: Ultrahigh sensitivity laser Doppler velocimetry with a microchip solid-state laser.
abstract: Highly sensitive laser Doppler velocimetry featuring the simultaneous measurement of light-scattering objects moving at different velocities and vibration sensing based on Doppler-shifted light-injectioninduced intensity modulation in an externally pumped microchip solid-state laser is demonstrated.
