Question about Laser diode type 670nm.

Hello guys...I wanted to replace the laser diode type 670nm...but I couldn't find correct replacement...Can I replace it with higher than 670nm? Thanks in advance.

That will depend upon the application where you're replacing the laser.
However, this product (http://www.aixiz.com/store/product_i...roducts_id/234) comes very much close to 670 nm.

There are 670nm laser diodes with different formfactors here: http://www.roithner-laser.com/ld_diverse.html .

Enjoy your design work!
