LASER MICROSCOPIES Meaning and
Definition
-
Laser microscopies refer to a variety of advanced microscopic techniques that utilize laser light for imaging and analysis at a nanoscale level. These techniques involve the use of lasers in combination with various optical and detection methods to examine and analyze samples in both biological and non-biological fields.
One commonly used form of laser microscopy is confocal laser scanning microscopy (CLSM). In CLSM, a laser is used to focus light onto a specific point in a sample, and the emitted fluorescent light is detected by a photomultiplier tube or a similar device. By scanning the laser beam across the sample, a series of optical sections are obtained, which can be stacked together to generate three-dimensional images with high resolution and contrast.
Another form of laser microscopy is two-photon microscopy. This technique employs lasers that emit near-infrared light to excite fluorophores in the sample, allowing for deeper tissue penetration and reduced phototoxicity compared to traditional fluorescence microscopy. Two-photon microscopy is particularly useful in studying living tissues and dynamics within organisms.
Laser microdissection, another technique, uses a laser beam to selectively remove specific cells or structures from a sample for further analysis. This enables precise isolation of individual components, such as cells, layers of tissues, or organelles, which can be collected for various downstream applications.
Overall, laser microscopies provide researchers with powerful tools for imaging, manipulating, and analyzing samples at high resolution, allowing for detailed observation and investigation of nanostructures and cellular processes.

Etymology of LASER MICROSCOPIES
The term "laser" originates from the acronym LASER, which stands for "Light Amplification by Stimulated Emission of Radiation". It was first coined by Gordon Gould in 1957 to describe a concept he developed while working on microwave technology. However, it was Theodore H. Maiman who built the first working laser device in 1960.
The word "microscopy" stems from the Greek words "mikros" (meaning small) and "skopein" (meaning to look or view). Microscopy refers to the scientific technique of using microscopes to magnify and study small objects, such as cells, tissues, or particles, which are not visible to the naked eye.
When combined, "laser microscopy" refers to the use of laser technology in microscopy, where lasers are utilized to illuminate specimens and improve image resolution and contrast.
