The Mira 900 is a Titanium Sapphire tunable femtosecond laser pumped by the Verdi V-10, 10 Watt pump.
\nThe pulsed output has an average power of over 1.6 Watt.
\nA figure of the Mira, with a block diagram of the main functioning components is shown in figure 1. The Mira uses a passive modelocking scheme; a saturable absorber, and a simple slit to reject continuous wave(CW) operation, and amplify short pulses. Additionally, the Mirra can be configured for femtosecond, or picosecond pulsed operation.<\/h4>\n

A femtosecond oscillator can be summarized as a \u00ab\u00a0black box\u00a0\u00bb in which there are only optical elements such as mirrors, prisms, lenses and a crystal with 2 extra-ordinary properties.<\/h4>\n

A continuous laser is injected into this \u00ab\u00a0black box\u00a0\u00bb and a train of femtosecond pulses comes out!<\/h4>\n

All the dynamics operate around this famous crystal that is titanium-sapphire!It has the power to emit a very large amount of longitudinal frequencies and couple them together by the KERR lens effect!
\nThis crystal is the \u00ab\u00a0holy grail\u00a0\u00bb of laser physics.<\/h4>\n<\/div><\/section><\/div>\n
