摘要：
An ultrafast laser system includes a seed laser that provides a signal laser pulse and a fiber-based first chirped reflective Bragg grating that reflects the signal laser pulse propagating along a first path and produce a stretched laser pulse longer than the signal laser pulse. A grating frequency of the first chirped reflective Bragg grating varies along the first path. An amplifier can amplify the stretched laser pulse and output an amplified laser pulse. A second chirped reflective Bragg grating can reflect the amplified laser pulse and produce a compressed laser pulse shorter than the amplified laser pulse. The amplified laser pulse propagates along a second path in the second chirped reflective Bragg grating. A grating frequency of the second chirped reflective Bragg grating varies in an opposite direction along the second path as the grating frequency of the first chirped reflective Bragg grating varies along the first path.
