    Abstract: A chirped-pulsed amplification laser device includes a fiber laser driver, a laser head, and a delivery fiber that guides amplified stretched laser pulses from the laser driver to the laser head. The fiber laser driver includes a seed pulsed laser, a pulse stretcher, and an optical power amplifier. A chirped fiber Bragg grating compressor in the laser head includes a fiber terminal section configured to minimize broadening of the amplified stretched laser pulses, a chirped fiber Bragg grating section connected to the fiber terminal section and configured to compress and reflect amplified stretched laser pulses to produce reflected laser pulses with compressed pulse durations, and a collimator housing configured to fixedly hold a collimator lens and a ferrule. The ferrule holds the fiber terminal section tilted relative to an optical axis of the collimator lens.

    Abstract: Techniques and devices for producing short laser pulses based on chirping and stretching of short seed laser pulses and subsequent power amplification. Such laser pulses with relatively narrow spectral bandwidths can be used in certain laser applications where narrow spectral bandwidth laser pulses are advantageous. In the examples described in this document, the generated laser pulses with relatively narrow spectral bandwidths may have relatively long pulse durations (e.g., greater than 1 ps) due to the stretching operation in the pulse generation.
