Chinese Blog Post - Sept

Hello, I am looking for an article to be written entirely in Simplified Chinese with about 300 or more words. The content needs to be 100% original and the topic should be about lasers and how they are used. Please highlight the keywords used in the article. The article needs to include the following 2 keywords: i. 半导体激光器 ii. 激光光束诊断 Since this is a pretty straightforward project the max price should only be $35.00. Although if the quality of the work is good and the project gets completed on time, there will absolutely be more opportunities like this every month. Thanks!
