Abstract

We report on a diode-pumped double-slab Yb:KYW regenerative amplifier with combined gain spectra and intracavity dispersion compensation. At repetition rates > 20 kHz an average power of up to 5 W after compression was generated, resulting in a maximum pulse energy of 250 µJ. Pulse durations of around 190 fs were achieved by using a GRISM compressor with a transmission efficiency of 90%.

Setup of the double-slab regenerative amplifier with combined gain spectra (schematic). C1 and C2: laser crystals in “Np” and “Nm” orientation; pump light is polarized along Nm in both cases; FM: flat mirror; CM: concave mirror; DM: dichroic flat mirror; TFP: thin film polarizer.

Output spectra (each normalized to maximum intensity) for different numbers of round-trips (RT) at a repetition rate of 100 kHz. For three different states of operation at (a) 21 RT, (b) 30 RT and (c) 39 RT the corresponding values of the pulse energy are given.

Operation with intracavity dispersion compensation and without readjustment of the compressor at a repetition rate of 20 kHz. (a) Energy of compressed pulses vs. number of round-trips. (b) Temporal characterization of compressed pulses: width of intensity autocorrelation trace (blue triangles) and corresponding calculated pulse duration (black squares) and calculated FTL pulse duration (red dots) vs. number of round-trips.

Amplified pulses after 42 resonator round-trips at a repetition rate of 20 kHz with a pulse energy of 250 µJ after compression. (a) Output spectrum dominated by the Np-peak at λ = 1038 nm. (b) Measured intensity autocorrelation function (ACF) of the compressed pulses (solid) and calculated FTL ACF (dashed).
