Scientists have developed a new technique to generate more powerful, more energy efficient and low-cost pulsed lasers. The technique has potential applications in a number of fields that use pulsed lasers including telecommunications, metrology, sensing and material processing. Any application that requires optical pulses typically needs waveforms of a specific repetition rate, pulse duration, and pulse shape. It is often challenging to design and manufacture a laser with these parameters exactly as required. Even when a suitable solution exists, the size, the complexity and ease of operation of the laser are further critical considerations. he new method works on a fundamentally different principle to existing pulsed lasers.
