Improving Laser Efficiency: A Higher Dopant Concentration Ratio

The logic in this paragraph is clear and straightforward. It states that research has shown that a higher dopant concentration ratio is better for laser efficiency, and as a result, the authors chose a dopant ratio of 25 instead of the typical value of around 15.

However, the paragraph can be improved with some English language polishing. Here is a revised version:

Furthermore, studies have indicated that a higher dopant concentration ratio CTm / CHo can enhance laser efficiency [22]. Therefore, we opted to use a dopant ratio of 25 in our research, which is higher than the typical value of around 15 [23].
