TL;DR: In this article, the construction principles and performance of a pulsed time-of-flight (TOF) laser radar based on high-speed (FWHM$ 100 ps) and high-energy (sim$ 1 nJ) optical transmitter pulses produced with a specific laser diode working in an enhanced gain-switching regime and based on single-photon detection in the receiver is discussed.

TL;DR: In this paper, a multiple quantum well laser diode utilizing an asymmetric waveguide structure with a large equivalent spot size of ∼3μm was shown to give high energy (∼1 nJ) and short (∻100ps) isolated optical pulses when injected with <10 A and ∼1-ns current pulses realized with a MOS driver.

TL;DR: In this article, a compact laser pulser emitting ∼100 ps, ∼10 W pulses at >100 kHz is presented, where the high pulsing frequency is achieved using a MOSFET-based current driver, whereas the high pulse power is a merit of the used laser diode with an asymmetric waveguide structure leading to enhanced gain switching.

TL;DR: In this article, a pulsed TOF laser radar utilizing the single-photon detection mode has been implemented, and its performance is characterized, and the characterization results demonstrate a distance measurement accuracy of +/−0.5

TL;DR: In this paper, the feasibility of a laser diode with a large equivalent spot size in single photon detection based laser ranging was demonstrated to a non-cooperative target at a distance of a few tens of meters.
