The generation of yellow laser mostly uses the laser transitions from ()~4F_(3/2) to ()~4I_(11/2) and ()~4F_(3/2) to ()~4I_(13/2) of Nd~(3+) doped crystal and adopts the technology of intracavity-frequency-mixing, but there are many difficulties for obtaining the high quality facula and high stable output power, thus the method of intracavity-frequency-doubling is proposed.

子宫内膜癌腔内放射治疗
子宫内膜癌腔内放疗有：①传统方法，使用治疗子宫颈癌的治疗容器，如宫腔管及阴道容器，(容器有：斯德哥尔摩盒式、巴黎弓形、曼彻斯特卵圆形、北京型等)。其缺点是子宫角部受量不足；②Heyman倡导宫腔填充法，将含有镭或其他同位素的金属小囊填满于子宫腔内，使宫腔各壁均能得到高剂量照射，可使单纯放疗效果由30%～40%增至60%以上；③腔内后装放射治疗。剂量：现在采用高剂量率及中剂量率，摒弃低剂量率。高剂量率：Ⅰ期：A点(位于子宫旁三角区内，代表宫旁正常组织受量)总剂量36～40Gy，F点(位于宫腔放射源的顶端旁开子宫中轴2cm，代表肿瘤部受量)总剂量40～45Gy。腔内治疗分5～6次进行，每周1次，每次剂量大致相同。Ⅱ期～Ⅲ期：A点及F点总剂量均为45～50Gy，腔内治疗分6～7次，每周1次，每次剂量大致相同。中剂量率：Ⅰ期：A点总剂量率45～50Gy，F点总剂量50～55Gy，腔内治疗6～8次，每周1次，每次剂量基本相似，Ⅱ～Ⅲ期：A点及F点剂量均为55～60Gy，腔内治疗7～8次，每周1次，每次剂量大致相同。腔内照射多用137Cs、60Co等。
