The YAG laser with the contact sapphire probe has definite advantages over other laser systems. Compared with CO2 lasers, its flexible fiber delivery system can be more easily used. Moreover, the laser can be used within a liquid environment with the production of little or no smoke. The probes allow a contact technique with discrete transfer of energy that can be modulated by the probes chosen and the wattage used. Unlike with the CO2 laser, energy delivery to unintended targets downstream is rarely a problem. As with other lasers, the initial purchase of a YAG laser is expensive. The YAG laser, however, has been used widely in lower generative tract surgery to the cervix and vulva and within the uterus itself for ablation procedures. It is also used with increasing frequency by other subspecialty groups performing urologic procedures, ophthalmologic procedures, and even general surgery. Therefore, its overall cost-effectiveness within an institution is probably excellent.
带有接触式蓝宝石探头的YAG激光相对于其他激光系统具有明显优势。与二氧化碳激光相比，其灵活的光纤传输系统使用起来更加便捷。此外，该激光可在液体环境中使用，产生的烟雾很少或几乎没有。探头允许采用接触技术，能量离散传递，可通过所选探头和使用的功率进行调制。与二氧化碳激光不同，向下游意外目标传递能量很少成为问题。与其他激光一样，YAG激光的初始购置成本很高。然而，YAG激光已广泛应用于下生殖道至宫颈和外阴的手术，以及子宫内的消融手术。其他进行泌尿外科手术、眼科手术甚至普通外科手术的亚专业组使用它的频率也在增加。因此，它在一个机构内的总体成本效益可能很高。
