Ti∶Sapphire Femtosecond Pulses Pumped Directly by Green Diode Lasers
The laser beams emitted from a pair of 520 nm/1.45 W green diode lasers are shaped and focused on a Ti∶sapphire laser crystal to complete the pumping process. The intracavity dispersion is compensated by using the GTI (Gires-Tournois interferometer) mirrors. The stable Kerr-lens mode locking state is achieved with an output pulse width of 91 fs, an output power of 208 mW, and a single pulse energy of 1.59 nJ. The narrowest pulse width of 82 fs is further realized after the optimization of cavity-type parameters and the maximum output power reaches 232 mW when the cavity length is shortened.
