This is a quick explanation of a multi layered version that I would use to give the light beam some depth.

The Wide yellow beam layer is made with the Rectangular Marquis Tool.
I set the tools feather to about 15px and make a selection.

Fill the selection with yellow.
Hit Cmd/Cntrl + D to deselect.

Then set the layers blending mode to Hard Light, and then lower the layers opacity to 44%.

Next I add a layer mask and use the Gradient Tool set to the 'Foreground to transparent' preset, to make the edges a bit more translucent.

Next I create a new layer above the previous layer, this will be the narrow Yellow beam.
I again use the Rectangular Marquis Tool with the feather set to 8px.
Make a selection...

Fill the selection with Yellow, set to Hard light, lower it's opacity to 35%.
Screen Shot 2017-01-21 at 12.34.03 AM.png

On a new layer above the last, repeat the above process for a white beam.
Set the white beam layer to Hard Light, and the opacity to 30%.

Create a new layer between the two yellow beam layers.
Select your Elliptical Marquis Tool and set the feather to 2px.
Make a selection....
Screen Shot 2017-01-21 at 12.38.23 AM.png

Fill with white, add a Gaussian Blur, set the opacity to 85%
Screen Shot 2017-01-21 at 12.39.58 AM.png

I would then group all of these layers and add a layer mask to the group.
With the Brush Tool set to black, I would mask out the subject.

(note: Mind you, I didn't add in all the reflections and so on, and you could play with the layer modes and settings, I
just thought these looked best for the image I chose to use as an example.)

This is only one way to do this.

Sorry, I assumed you knew this. Anytime you use a gradient on a LAYER MASK, the foreground/background color will always be black and white! There are a few occasions that you might use gray.

Based on what you have posted above, it looks pretty good.

One thing I did forget to mention is that I did move the light beam layers upwards using the Move Tool.

On second look, I can't tell your layer mask does not look right.

It seems to have a T shape...

When it needs to look like mine above with two, full length gradients on either side.
Screen Shot 2017-01-21 at 8.08.01 AM.png

Be sure your using a linear gradient and you will have to pull the gradient from the right and left edges towards the middle while holding the shift key.

Again, I'm sorry..............I assumed you already knew this.

One quick thing!!

When you add the layer mask to the light beam, does it look like this?
NOTE: This is a new example and not from the tutorial!

The thought occurred to me that you may not have turned off your selection (Cmd/Cntrl + D) before you added the layer mask. Be sure and turn off the selection before adding the layer mask!!!!

OK, you have the layer mask correct, but your not using black as your foreground color on the Gradient Tool.

Red Arrows: Notice here that your Foreground color is white and your gradient is yellow................these should both be black!
Blue Arrow: Uncheck the reverse box.
Screen Shot 2017-01-21 at 7.00.09 PM copy.png

ALSO..........make sure you select the layer mask when you add the gradient.
