帮我检查下面这句话的逻辑和语法错误并润色尽量减少compact这个单词的重复：Therefore we designed a compact side-pumped laser head based on a ceramic diffusive optical reflector DOR and the schematic is illustrated in Fig1 The laser head

Therefore, we have developed a compact laser head that utilizes a ceramic diffusive optical reflector (DOR) for side-pumping. The schematic of the laser head is depicted in Fig. 1, and it consists of a Tm,Ho:YAG rod, a glass flow tube, a DOR, and three pump modules. By eliminating guiding elements, we have minimized the risk of extra optical loss, resulting in a laser head that is both compact and rugged. Additionally, the absence of guiding elements makes it easy to adjust the laser head.
