Pulsed laser ablation in liquids is a very powerful and versatile physical technique for the synthesis of colloidal nanoparticles (NPs), having a number of unique features including an exceptional purity of the NPs surface, high colloidal stability without using of any ligands and unusual surface chemistry. The method of laser ablation profits from a natural generation of nanoclusters under irradiation of a solid target by laser pulses in various liquids. Among many useful types of the laser-synthesized NPs, a class of light-absorbing colloidal nanomaterials is especially interesting as it has lots of practical applications in biomedicine, renewable energy and photocatalysis. Here we present our recent results in laser ablative synthesis of NPs having high optical absorption in visible and near-infrared spectral ranges. Optical and structural properties of the laser-synthesized NPs based on alternative plasmonic materials (transitional metal nitrides and lanthanoid borides) and MXenes will be discussed. Moreover, an assessment of the NPs in photothermal therapy, photoacoustic visualization and solar energy harvesting will be also presented.
