The distributed Bragg pulse shaper (DBPS) is a series of electrically switchable Bragg mirrors on a semiconductor waveguide. The DBPS encodes data packets using parallel electrical signals to set the states of the Bragg mirrors. A broad-band source p

Recent advances of high power and narrow bandwidth laser diodes emitting at 1.9 μm open the path to direct diode pumping of Ho 3+ :YAG lasers. The usual method to pump such laser is to use thulium fiber laser which has an excellent beam quality with
