hi
Can I measure distance by using a laser transmitter module or a laser dot diode module? if yes then please provide details
thank you

I moved your topic to an appropriate forum category @raushan_1995.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Triangulation/parallax

Read up on Time Of Flight measurement. (TOF)

For intermediate range, use TFmini or Garmin Lidar Lite LED. For longer range, LIDAR-Lite v3 - SEN-14032 - SparkFun Electronics

I assume something like this is difficult to build yourself... Light travels so fast that the microcontroller can't time it.

Yes, if your laser device can be pulsed by your Arduino and if you have a receiving device that can indicate it received the reflected light from your laser.
Once you subtract the laser delay time and the receiving sensor delay time, you can measure the exact time the light takes to travel twice the distance. Then you can compute, not measure, the distance.
