狭窄光学共振的飞秒脉冲激光稳频性研究

稳频的连续飞秒脉冲激光器以狭窄的光学共振作为水准基点,这种激光器具有稳定频率成分的宽带光谱和大功率的超短脉冲,能够有效的快速转变频率。在本文中可以看出这种双光子吸收共振使氢原子1S-2S能级之间跃迁的钛宝石激光器稳频飞秒脉冲振荡机制。

Study on the Frequency Stabilization of Continuously Repetitive Ultrashort-pulse Laser by the Narrow Optical Resonances

Frequency Stabilization of Continuously Repetitive Ultrashort-pulse Laser serves as a basis for Narrow Optical Resonances. Continuously Repetitive Ultrashort-pulse Laser has a broad spectrum with stable frequency and a great power with Ultrashort-pulse which can transmit the frequency effectively. The result of this research shows that resonance absorption of two-photons can make the continuously repetitive ultrashort-pulse laser by Ti： sapphire transit between energy level 1S and 2S of hydrogen atom.
