“…The large absorption bandwidth of Ti:Sa enables several pumping sources that However, technology evolved towards the use of high power pulsed sources. These needs meant a shift to the use of flash-lamps [57] or colorant lasers [58]. Nowadays, the most extended way of pumping a Ti:Sa laser, both pulsed or CW, is through the second harmonic line of Nd:YAG (532 nm).…”
