Femtosecond real-time spectroscopy

Femtosecond real-time spectroscopy requires sophisticated experimental and theoretical techniques. Some experimental basics are given in this chapter. A few remarks on the theoretical basics relevant to the investigations presented in this book are included in the second part of this chapter. It should be pointed out that this treatment is intended to give a rapid overview but is not at all complete. Those readers who are looking for a more detailed description of these fascinating experimental and theoretical techniques should therefore consult the references given in Sects. 2.1 and 2.2.
