Can shining light deeper into the brain stimulate the brain?

An international team of researchers has developed a way to shine light at new depths in the brain. It may lead to development of new, non-invasive clinical treatments for neurological disorders and new research tools.
The new method extends the depth that optogenetics — a method for stimulating neurons with light — can reach. With optogenetics, blue-green light is used to turn on “light-gated ion channels” in neurons to stimulate neural activity. But blue-green light is heavily scattered by tissue. That limits how deep the light can reach and currently requires insertion of invasive optical fibers.

So far, in mice, yes.
I'm glad to see that they're using less energetic wavelengths in medical procedures, including imaging technologies.
I'm no doctor, but I believe the more energetic the wavelength, the more disruptive it is to cells.
X rays are very energetic.
The other end of the spectrum has longer wavelengths.
