Go to File > New and create a new image with a black background.
Choose lime green as your foreground colour and black as your background on the colour palette.
Click the text tool (it looks like a T), and then type the text you want on your image. In the top right corner of the screen, click the check/tick, and then look at your layer palette in the bottom left.
Select the text. You can do this by clicking the Magic Wand tool and clicking just underneath your text to create a floating dotted line around the edge. Then hold down the Shift button on your keyboard and click inside any solid letters such as Os and As to select the middles of those too.

Go to Filter > Blur > Radial Blur and choose 100, Zoom and Best before clicking Ok.

Go to Select > Deselect
Go to Layer > Flatten Image, then save. This is the final result:
