本文介绍了用于鼓膜切开术和显微外科手术的3 μm激光器的研制和实施。研究了两种不同的激光器。第一种是掺铒连续波锆酸盐玻璃光纤激光器，由970 nm半导体激光器泵浦，在2.76 μm波长处发射出大于1 W的连续波功率，并伴随有绿色非相干发射，作为一种方便的可见光照明光束。第二，用970nm半导体激光器泵浦的1W连续Er：YAG固体激光器，在2.94 μm波长处获得了大于1W的连续激光输出，与水的最强红外吸收峰重合。运行CW，这两种激光器预计将避免与脉冲激光器相关的响亮的声冲击。用Er：YAG激光对麻醉的豚鼠进行鼓膜切开术，并记录激光的效果。对激光消融的鼓膜、软组织和骨组织进行组织学检查。组织学结果表明，CW Er：YAG激光是一种新的鼓膜切开术工具的潜在候选者，可能用于耳科显微手术，但可输送功率水平需要增加到2 W（或更高）水平。这项工作得到了NIH SBIR资助号5R44DC004899的资助。
This paper describes the development and implementation of 3 μm lasers for myringotomy and microsurgery. Two different lasers were investigated. The first, an Er-doped, CW zirconate glass fiber laser optically pumped by a 970 nm diode laser, emitted > 1 W of CW power at 2.76 μm with concomitant green incoherent emission that served as a convenient visible illumination beam. The second, a 1 W CW Er:YAG solid-state laser also optically pumped by a 970 nm diode laser, emitted > 1 W of CW power at 2.94 μm, coincident with the strongest infrared water absorption peak. Running CW, both lasers are expected to avoid the loud acoustical shocks associated with pulsed lasers. Myringotomies were carried out with the Er:YAG laser on anaesthetized guinea pigs and the effects of the laser were documented. Laser ablated samples of tympanic membrane, soft tissue and bone were histologically examined. Histology results indicated that the CW Er:YAG laser is a potential candidate for a new myringotomy tool and possibly for otologic microsurgery, but deliverable power levels need to be increased to the 2 W (or higher) level. This work was funded under NIH SBIR Grant No. 5R44DC004899.
