A Ti:Sapphire crystal in the centre of a multipass amplifier Quantronix Odin is pumped by 5W green beam (faintly visible coming from right), amplifies femtosecond pulses that pass it several times under different angles (invisible on the photo) and loses part of energy as red fluorescence light
Femtosecond pulses generate multiple angle-resolved colour patterns when focused; note their fan-out angle is even higher than that of the focused las
