"Mid-IR femtosecond pulse generation on the microjoule level up to 5 µm at high repetition rates"
M. Bradler, C. Homann, and E. Riedle
Opt. Lett. 36, 4212 (2011).


Abstract:
We show efficient generation of mid-IR pulses tunable between 1 and 5 μm from 100 kHz class femtosecond systems. The concept can be applied to various sources, particularly based on Ti:sapphire and the newly evolving Yb+ lasers. The mid-IR pulses are generated as the idler of a collinear optical parametric amplifier pumped by the laser fundamental. The seed for this amplifier is the idler of a previous amplification stage pumped with the second harmonic and seeded with a visible continuum. This enhances the energy and allows us to influence the bandwidth of the final output. Pulses with microjoule energy and Fourier limits of 50 fs are achieved.
