【摘要】 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.更多还原

【Abstract】 The scheme for synchronizing Ti:sapphire femtosecond laser and Nd:YVO₄ picosecond laser is discribed. Sub-ps jitter is obtained, based on which broad-band femtosecond blue-light laser of 460?nm is generated through mixing two laser pulses in the BBO crystal. The technique not only shows a general way of synchronizing lasers of completely different wavelength and pulse width, but also demonstrates a new scheme for generating ultra-short laser with new wavelength through nonlinear frequency mixing.更多还原
