Need help with Laser Driver Voltage with Specific 3-PIN Diode
This may work.. On the diode datasheet, you can see that the laser power graph only goes up to 280mA, but your constant current source is going to provide 2500mA. I would suggest you find a 250mA constant current source to correctly use this diode.

Edit 9/27: the link to the old sheet for the power supply is broke, and I was redirected to the new datasheet. anything below is strictly the new sheet.

There  appears to be a 5V analog control on the module that I did not see before. Using this, It would be possible to modulate the laser diode's supply using modulation, such as a 5V PWM signal, or even a voltage divider. If you decide to go the voltage divider route, then I would use values of 1k and 9k.
