Similarities and differences between Q-switched technology and mode-locked technology

The similarities and differences between the two technologies lie in the differences in definitions and mechanisms.

1, different definitions: Q-switched technology refers to the technology of adjusting the Q value of laser; Mode-locking technology is an important technology for laser to generate ultrashort pulses.

2. Its mechanism is different: Q-switched technology is a technology that compresses laser energy into pulses with extremely narrow width to emit, which can increase the peak power of light source by several orders of magnitude. Mode-locked technology uses mode-locked devices to compress laser pulses to a very short time, thus improving peak power.
