Compact, inexpensive, visible diode laser source of high repetition rate picosecond pulses

We discuss the techniques and describe the circuitry to build a visible diode laser picosecond light source. The rf circuitry is easy and inexpensive to build, and the final package is quite compact. Stable, low jitter, 108‐Hz trains of ∼100‐ps, 670‐nm optical pulses are therefore readily attainable.
