A laser beam pointed at the skin will produce ultrasound as a side effect by interacting with the tissues. This is how a photoacoustic tomography device works and is used for imaging tissues below the skin.
"technology works on a near infrared laser that is fired into tissue. The laser's energy, once absorbed by the tissues, generates heat, which in turn generates the photoacoustic signals that are picked up by an ultrasound transducer."

Do giraffes produce ultrasound to communitate?
Actually, Giraffes communicate using infrasonic sounds, i.e. sounds with a frequency BELOW the range of human hearing. Ultrasound would be ABOVE the human hearing range.Sources: Wikipedia

What is an Ultra-sound?
Ultrasound is sound with a frequency higher than the upper limit of human hearing. It can be directed inside an object and the reflected waves analyzed to produce an image. The most well known application of this technique is its use in sonography to produce pictures of fetuses in the human womb.
What does an Endorectal ultrasound produce?

What radiographic procedure employs high frequency sound waves to produce an image?
Are known as: Overtones
What are ultrasound?
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
