Sorry but that is not the way to do it.
(By connecting TTL to GND the laser will never come on).

Perhaps take a look through this thread as it contains a lot of info that may be of use to you.Diode Lasers. - F

Ops. I am sorry.
Wrong picture. Ttl and ground i left it open.
Its that ok?
I need information what in the max. Voltage from laser driver module to laser. In my case is voltage 6V. Is that ok?

You will have to ask the supplier of the laser / driver board to get the answer to that.

I contacted the seller.
But they do not have any data.
I give them negative feedback.
In the driver is posible to adjust power to laser and i dont now what is the maximum.
This is link where i buy this laser:

My advise is that you don't adjust anything.
With diode lasers it is the Current adjustment that is critical and as many before have found the difference between Bright and Blown is a very fine line.
If you don't know then don't adjust.
