A nanosecond electrical pulse energizes a laser diode, producing a short pulse of light. Triggering is accomplished via a fast-switching, avalanching transistor, which discharges an RC network with a time constant of 1 ns. The high voltage required to avalanche the transistor is generated by an efficient, low-ripple DC/DC converter. The DC/DC converter provides sufficient current to provide a pulse rate of 350 kHz.

Affordable Nanosecond Pulses
Laser pulse measured with an Osram SiPM detector and a Tektronix scope. The intrinsic pulse rise time and width are ≤400 ps and ≤1.5 ns, respectively.
Rep Rates from Hz to Hundreds of kHz
Energy per pulse as a function of triggered pulse rate for a typical device. Below 150 kHz, the energy per pulse is approximately constant and gradually declines at higher frequencies up to the maximum trigger rate of 350 kHz.
Time of Flight with a Silicon Photomultiplier and Nanosecond Pulsed Laser
In this video, we'll introduce two of our products with nanosecond time resolution: a silicon photomultiplier (Eikonal SIPM-01) and a pulsed laser diode (Eikonal NLD-01). Exploiting the nanosecond resolution, we'll set up a simple time of flight experiment to measure the speed of light on a table top.
