RESUMO
We demonstrate a near-infrared, femtosecond, diode laser-based source with kW peak power for two-photon microscopy. At a wavelength of 976 nm, the system produces sub-ps pulses operating at a repetition rate of 10 MHz with kilowatt class peak powers suitable for deep tissue two-photon microscopy. The system, integrated with a laser-scanning microscope, images to a depth of 900 µm in a fixed sample of PLP-eGFP labeled mouse brain tissue. This represents a significant development that will lead to more efficient, compact, and accessible laser sources for biomedical imaging.
