Changing from 532nm to 520nm 300mW Green Line Laser Module

I am trying to choose uniform beam distribution green line laser module, with extremely high power up to 300mW. If it is being made with quite small size, not the same as a larger DPSS laser system, while it would be made with super strong beam stability.
I gets very good advice from berlinlasers. I change my mind to choose 520nm green line laser. The direct diode emission is achieves much more stable green line in use. It is performing nice in my PIV measurement. If anybody who is looking for a more stable and powerful line laser, Berlinlasers green line laser would be a recommending choice.
