The second harmonic generation is performed using LBO crystal. The fundamental pulse is generated by ultrafast Yb-doped fiber laser system utilizing gain-narrowing compensation. The repetition rate of the second harmonic pulses is 3 MHz. As a result, the output power is 104 mW, and transform limit pulse width of the second harmonic is 39 fs.
