Realization of Ultra Short and Super Strong Laser
Realization of ultra short and super strong laser From the perspective of laser applications, the development of lasers is mainly to find higher power, shorter pulse width, and higher energy output. That is, the process of obtaining ultra-strong ultra-short laser pulses. The construction of ultra-short and ultra-strong lasers relies mainly on the development and innovation of laser amplification technology. Conventional lasers use Q-switching, mode-locking and other techniques to improve laser power output. To achieve laser output, it is first necessary to achieve particle inversion, and secondly to meet the energy gain greater than the loss. Q is the quality factor of the resonant cavity, which is used to measure the energy loss of the laser. The higher the Q value, the greater the optical loss of the resonant cavity. The corresponding laser threshold is higher. When the Q switch is in the off state, the inside of the cavity will accumulate more inverted particles at t...
