ABSTRACT

In fifty years, laser technology has made great progress, and its many applications makeit essential in everyday life. However, this technology is still open to numerous developments. Across multiple applications, there is particular focus in the field of medicine, for diagnosis for tailored therapies, and as a research tool in biology. Whereas its use is now well-demonstrated in ophthalmologic and dermatologic treatments, and surgery, one of the most fascinating aspects of laser technology in the field of biology emerged in the late 1990s with the development of devices able to perform fine dissections of biological tissues using a laser beam. Lasers have a wide and growing range of applications in medicine. In this paper medical applications of Lasers are discussed. Lasers are wonderful devices with enormous application potential. Lasers have a wide and growing range of applications in medicine. The use of lasers in medical diagnosis and treatments is known as laser medicine. Their increasing use in medicine is driven by new technology and a better understanding of the interaction of laser light with living tissue. Being faster and less invasive with high precision, lasers have penetrated most medical disciplines during the past half century, including dermatology, ophthalmology, dentistry, otolaryngology, gastroenterology, urology, gynecology, cardiology, neurosurgery and orthopedics. This article gives an insight into the basic principle, characteristics and medical applications of lasers. Laser spectroscopy provides many possibilities for multidisciplinary applications in environmental monitoring, in the ecological field, for food safety investigations, and in biomedicine. The paper gives several examples of the power of multi-disciplinary applications of laser spectroscopy as pursued in our research group. The studies utilize mostly similar and widely applicable spectroscopic approaches. Air pollution and vegetation monitoring by lidar techniques, as well as agricultural pest insect monitoring and classification by elastic scattering and fluorescence spectroscopy are described. Biomedical aspects include food safety applications and medical diagnostics of sinusitis and otitis, with strong connection to the abatement of antibiotics resistance development.
