Create a sci-fi laser light in PHOTOSHOP-PS tutorial

The creation process is very simple and cannot be completed in the following three simple steps. The technology includes some basic layer mixing. the process of selecting and creating painting skills is very simple and cannot be completed in just three simple steps below. Techniques include some basic layers mixing, selection, and painting skills.
The following is the final result. I have a preview of this tutorial:

Okay, let's get started!
Step 2
Create a new file with a black background (the size is not really important in this tutorial), create a new layer, use the rectangular box selection tool to draw a selection, and fill it with the selected color:

Deselect the filter to apply the following Gaussian blur filter settings to this layer:

Then compress it with the free transform tool, as shown below:

If you are not satisfied with the selected color, you can use the color/saturation adjustment (press Ctrl + U) to slightly adjust the color. Then some parts of the wire are removed with soft erasers, as shown below:

Copy this layer once and further compress it until it forms a slim line:

You will have the following impact:

Step 2
Create a new layer and draw a point over line with a soft white brush, as shown in:

When you set this new vertex layer as the top layer of a clipboard mask, you will have the following effects:

Create another image and compress it with a white brush, as shown in:

Change the layer blending mode to "overlay". if you copy this layer about 3-4 times, you will have the following effects:

Step 2
Now we want to add some airflow around the laser effect-you can either use a cloud filter (with a 30 pixel feather cable tool hybrid) to present some cloud lasers, or you can use a free cloud/smoke brush (you can find many of them on the Internet) to add some of its cloud effects:

Then, use a deformation tool to warp the cloud and stretch it to form a flow effect:

Here is what you aim to achieve:

Okay, we're done! Group all the above layers to a folder and add it to your design!

You can adjust the opacity of the original laser base layer (the first layer we created in this tutorial) to fade out, or compress the free layer Group conversion tool to reduce its height and width:
