Several options are available for picosecond excitation of the sample:

• lamp pumped Nd:YLF laser harmonics (523 nm, 349 nm, 262 nm) or output of optical parametric generator (210 – 2300 nm), pumped by this laser, with pulse duration of 8 ps and pulse repetition rate of 10 – 20 Hz
• lamp pumped Nd:YAG laser harmonics (532 nm, 355 nm, 266 nm) or output of optical parametric generator (210 – 2300 nm), pumped by this laser, with pulse duration of 20 ps and pulse repetition rate of 10 – 20 Hz
• diode pumped Nd:YAG laser harmonics (532 nm, 355 nm, 266 nm) with pulse duration of 80 ps and pulse repetition rate of 1kHz.

需要用超高速条纹相机或高速光电倍增管来记录皮秒时间分辨光谱仪的发光

时间分辨吸收光谱测量可以设计成泵浦-探针结构，The measurements of time resolved absorption could be arranged in pump-probe scheme. Output of optical parametric generator or laser exited Xe luminescence could be used as pump beam. The relaxation kinetics could be obtained from single pulse by the streak camera or acquired by scanning the delay between pump and probe pulses with motorized delay line.
