Several options are available for picosecond excitation of the sample:

• lamp-pumped Nd:YLF laser harmonics (523 nm, 349 nm, 262 nm) or 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 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 1 kHz.

A streak camera or fast photomultiplier with digital oscilloscope can be used for registration of time-resolved picosecond luminescence.

Measurements of time-resolved absorption can be arranged in pump-probe scheme. Either output of optical parametric generator or laser-exited Xe luminescence can serve as a pump beam. Relaxation kinetics is obtained from a single pulse by streak camera or by scanning the delay between pump and probe pulses with motorized delay line.

Specifications

1. Streak camera option

This alternative enables single shot measurement of time- and spectrally- resolved spectra.

2. Fast photomultiplier option

This alternative enables single shot measurement of a time-resolved trace at specific wavelength.
