Hello Zhan,

Point Source makes a good 25 mw 405 nm Diode Pumped Solid State laser that we have been using for the last year and a half with relatively no troubles. 5 years is a long time in relation to technical advances, so I wouldn't worry too much about not being able to get the same model. Good luck!

Pete
