第二代飞秒激光器自１９世纪发明闪光摄影术以来，短光脉冲一直作为冻结快速发生事件运动的手段。１９６０年脉冲激光器的发明，使研究人员能够详细了解在纳秒和皮秒时间尺度上发生的许多光弓没过程。自然界的许多事件都在更快时间尺度上发生，因而也就促进了超短脉冲激光...
Second-generation femtosecond laser Since the invention of flash photography in the 19th century, short-pulse light has been used as a means of freezing fast-moving events. The invention of the pulsed laser in 1960 allowed researchers to learn more about the many processes that occur on nanosecond and picosecond time scales. Many events in nature occur on faster time scales, thus facilitating ultra-short pulse lasers.
