Abstract

We present for the first time a SESAM-modelocked thin-disk laser (TDL) that incorporates two gain materials with different emission spectra in a single TDL resonator. The two gain media used in this experiment are the sesquioxide materials Yb:Lu2O3 and Yb:Sc2O3, which have their spectral emission peak displaced by ≈7 nm. We can benefit from a combined gain bandwidth that is wider than the one provided by a single gain material alone and still conserve the excellent thermal properties of each disk. In these first proof-of-principle experiments we demonstrate pulse durations shorter than previously achieved with the single gain material Yb:Lu2O3. The oscillator generates pulses as short as 103 fs at a repetition rate of 41.7 MHz and a center wavelength of around 1038 nm, with an average output power of 1.4 W. A different cavity layout provides pulses with a duration of 124 fs at an output power of 8.6 W. This dual-gain approach should allow for further power scaling of TDLs and these first results prove this method to be a promising new way to combine the record output-power performance of modelocked TDLs with short pulse durations in the sub-100 fs regime.

(a) Average output power of ultrafast thin disk lasers as a function of the achieved pulse duration. The two results presented here are highlighted with red crosses and are based on combining two different gain materials in the thin disk geometry within one laser resonator. (b) Thermal conductivity as function of FWHM emission bandwidth. The advantage of Yb:LuO and Yb:ScO (red circles) compared to their stoichiometric mixture Yb:LuScO is a better thermal conductivity, here given for a doping concentration of 8·1020 cm−3.

Fig. 2
Fig. 2

(a) Microscope photo of the Yb:LuO-disk (top) and the Yb:ScO-disk (bottom). The high-quality Yb:LuO crystal does not show any visible grain boundaries, which is in contrast to the Yb:ScO crystal. (b) Interferometric measurement of the surface flatness deviation of the two disks. The measurement is performed at 1 bar of water pressure at the backside of the disk. The Yb:LuO-disk (top) has a perfect spherical surface whereas the Yb:ScO-disk shows slight astigmatism. The pump spot on the corresponding disk is marked with a dotted black circle. (c) Cavity design of the dual-gain resonator supporting fundamental transverse mode operation up to 10 W cw. The two disks are separated by a distance of ≈1.15 m. The SESAM and the output coupler are the two end mirrors of the linear cavity. We measured for all experiments an M2 < 1.2.

(a) SESAM parameters: recovery time (τ1/e), saturation fluence (Fsat), modulation depth (ΔR) and nonsaturable losses (ΔRns) measured with a pulse duration of 1 ps at a center wavelength of 1030 nm. Taking into account the red shift of the SESAM, the values measured at 20 °C are a good approximation of the parameters of our experiment operating the SESAM at a temperature of 40 °C and a center wavelength of ≈1038 nm. (b) Left axis: Linear reflectivity spectra of the SESAM measured for different temperatures. The reflectivity exhibits a broad wavelength dependence as expected from low-temperature MBE growth and clearly shows the red shift of the quantum well bandgap with 0.38 nm / °C. Right axis: Modelocked spectrum using the SESAM at three different temperatures. At 20 °C and 30 °C the two separate gain materials at maximum emission wavelength of 1034 nm (Yb:LuO) and 1041 nm (Yb:ScO) are not fully locked because the SESAM does not provide a large enough modulation depth. We therefore observe cw instabilities at 1034 nm and 1041 nm (top and middle). For a fully modelocked spectrum the modulation strength of SESAM had to be increased with the higher temperature of 40 °C (bottom).

(a) Noncollinear autocorrelation measured for the highest average output power of 8.6 W reveals a pulse duration of 124 fs. (b) The corresponding spectral bandwidth of 10.1 nm FWHM is centered at 1038.5 nm (red-black striped) in between the two emission cross-section maxima of Yb:LuO (blue) and Yb:ScO (yellow). This clearly demonstrates that both gain materials contribute to the spectral shape of the pulses. (c) Microwave spectrum analyzer shows a pulse repetition frequency of 41.7 MHz with a resolution bandwidth (RBW) of 1 kHz and in (d) with a RBW of 300 kHz over a larger frequency scan with no unusual features in the pulse train.
