利用主动同步方式实现了飞秒钛宝石激光器与皮秒Nd:YVO4激光器的同步,得到了时间抖动低于1ps的同步精度.在此基础上进行了两束激光的和频实验研究,产生了波长为460nm的宽带蓝光飞秒脉冲激光.这一技术不仅代表了实现不同波长、不同脉冲宽度激光同步的一般方法,而且也证明了通过和频、差频两束不同激光产生新波长超短脉冲激光的一种全新技术方案.
The synchronization of femtosecond Ti: sapphire laser with picosecond Nd: YVO4 laser was achieved by means of active synchronization, and the synchronization accuracy of time jitter less than 1 ps was obtained. Based on this, the sum frequency experiment of two laser beams was carried out and the wavelength Is 460nm broadband blue femtosecond pulse laser.This technology not only represents the general method of laser synchronization with different wavelengths and different pulse widths but also proves that the new wavelength ultrashort pulse laser can be produced by two different lasers of sum frequency and difference frequency A new technology program.
