In the past two decades, different types of lasers have been used for various medical/surgical procedures but lasers in Ophthalmology have always enjoyed a unique role since they offer new and innovative surgical capabilities to the ophthalmologist. Recently, "Excimer Lasers" such as Argon Fluoride and Krypton Fluoride have gained much enthusiastic support due to their capability of photoabilative tissue decomposition. There is ongoing research to detect the efficacy of this laser in making corneal incisions and keratorefractive surgery inspite of some newly discovered side effects. Nitrogen laser pumped dye laser coupled with frequency doubling technique can deliver ultra-violet laser energy in the wavelength range 250-330 nm. Its potential clinical use in the medical field has not yet been explored. The purpose of this research is to explore the capabilities of tunable ultra-violet radiation from a frequency-doubled Nitrogen pumped dye laser in potential eye surgery and establish optimum wavelengths for various ophthalmic surgical procedures.

在过去的二十年里，不同类型的激光器被使用 用于各种医疗/外科手术，但激光 眼科一直享有独特的作用，因为它们提供 为眼科医生提供新的和创新的手术能力。 最近，氟化氩、氪等“准分子激光器” 氟化物因其优异的性能而获得了广泛的支持 光致组织分解能力。 有 正在进行的研究旨在检测这种激光在制造方面的功效 角膜切口和角膜屈光手术尽管有一些 新发现的副作用。 氮激光泵浦染料激光器与倍频耦合 技术可以提供波长范围内的紫外激光能量 范围 250-330 nm。 其在医学领域的潜在临床应用 尚未被探索。 这项研究的目的是 探索可调谐紫外线辐射的能力 潜在眼中的倍频氮泵浦染料激光器 手术并确定各种眼科的最佳波长 外科手术。
