Photoacoustic imaging, a non-invasive technique that combines the advantages of optical and ultrasonic imaging, is revolutionizing the field of medical imaging. In this revolution, microchip lasers are emerging as a rising star in photoacoustic imaging research due to their unique advantages.

With their short pulse width, high peak power, and stable pulse amplitude, microchip lasers provide an ideal excitation source for photoacoustic imaging. Their sub-nanosecond pulse width ensures high-resolution imaging of photoacoustic signals in biological tissues, clearly revealing microvessels, tumors, and other fine structures. Additionally, their high repetition rate significantly improves the detection efficiency of photoacoustic imaging, making the imaging process faster and more accurate.

Furthermore, microchip lasers offer multiple wavelength options, enabling multi-wavelength photoacoustic imaging. This technique captures the light absorption characteristics of biological tissues at different wavelengths, providing richer physiological and pathological information to support early disease diagnosis and treatment.

Notably, microchip lasers have been integrated with technologies like spectral-domain optical coherence tomography, advancing the development of contact-free photoacoustic imaging. This innovation not only addresses the contact requirement of traditional photoacoustic imaging but also expands its applications, offering new imaging solutions for clinical fields such as ophthalmology and neurology.

In practical applications, microchip lasers have demonstrated remarkable capabilities. For instance, a research team at Northeastern University at Qinhuangdao successfully obtained clear capillary imaging using sub-nanosecond microchip lasers provided by Beijing RealLight. This achievement not only validates the effectiveness of microchip lasers in photoacoustic imaging but also lays a solid foundation for their broader application in medical imaging.

In summary, microchip lasers have shown tremendous potential and value in photoacoustic imaging research due to their unique performance and advantages. With continuous technological advancements and expanding applications, we can confidently expect microchip lasers to play an even more significant role in photoacoustic imaging, driving innovation and progress in medical imaging technology.
