GENERATING LASER PULSES OF NARROW SPECTRAL LINEWIDTH BASED ON CHIRPING AND STRETCHING OF LASER PULSES AND SUBSEQUENT POWER AMPLIFICATION

摘要

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.
