Available from Aculight Corp. is a pulsed fiber laser that generates eye-safe, short pulses over a wide repetition rate range. Model PF1550-30 is suitable for laser-rangefinding, range-imaging-lidar, fiber optic sensing, communications and micromachining applications. It also can be used as a seed source for high-power amplifiers. Based on erbium-doped fiber technology, it delivers 1.54-µm light output via a single-mode fiber and generates 1-ns pulses at repetition rates between 100 kHz and 1 MHz. It produces 1 W of average power and 1.2 kW of peak power at 1 MHz. The laser measures 10 × 10 × 4 in. and weighs 15 lb. The company says that the device is rugged and virtually maintenance-free.
