The new Brightsolutions’ Vento series represent an ideal option for bathymetric LiDARs.

Indeed a shorter pulse duration is a desirable parameter for optimization of the longitudinal resolution, provided that the optical spectral linewidth becomes not too large to worsen the signal-to-noise ratio at the detection point. Since ~ 0.1 nm is a reasonable linewidth, sub-nanosecond-long actively Q-switched DPSS lasers providing multi-mJ energies in a close-to-diffraction limited beam profile and at a repetition rate of few kHz, such as the Vento series.
