激光已长期用于医学外科手术,其应用范围包括血管的烧堵到心脏打孔。现在激光诊断器件也扩展到生物影像和基础生物研究之类领域,超快激光使这些应用成为可能。最引人注目的进展或许是在光学层析术这一相当新的领域，它用超短激光脉冲探测体内异常，而不像其他技术那样采用对身 Laser has long been used in medical surgery, the scope of its application, including blood vessels blocking the heart to the hole. Laser diagnostic devices are now also extended to such areas as biological imaging and basic biological research, and ultrafast lasers make these applications possible. Perhaps the most dramatic advance in optical tomography is the relatively new field of ultra-short laser pulses that detect in-vivo anomalies rather than the one used in other technologies
