In histology, lasers are integral to confocal microscopy and multiphoton microscopy. Confocal microscopy uses laser light to scan samples and produce high-resolution, three-dimensional images of tissues. This technique is invaluable for studying the intricate details of cell structures and tissue architecture. Similarly, multiphoton microscopy employs lasers to excite fluorescent dyes within deep tissue layers, allowing for imaging of live tissues without significant photodamage.
