In this work, we introduce a technical approach to harness liquids for highly stable and efficient Supercontinuum Generation (SCG) at up to few hundreds of kHz. Using a differential pressure scheme, the velocity at which the liquid interacting with the laser is exchanged, is optimized to achieve pump source limited stability. This approach is validated by generating a SC in water pumped at the Fundamental Wavelength (FW) and the Second Harmonic (SH) of a Yb:KGW laser amplifier at 50 kHz and 100 kHz. In addition to its high stability, the resulting SC signal is more broadband and has a higher spectral intensity compared to the signals obtained with the established crystals Yttrium Aluminum Garnat (YAG) and sapphire.
