A team of researchers at St. Petersburg State University (SPSU) has developed what is believed to be an advanced new laser, Popnano.ru reported. It is said to be what?s called a boson cascade laser, developed at SPSU?s optics laboratory led by Alexey Kavokin. The laser is expected to have a broad range of applications. For example, it could be used to help treat skin cancer or guard areas against robbers or terrorists. According to Mr. Kavokin, there are skin cancer treatment methodologies that call for the use of lasers operating in a terahertz frequency range. However, the only such laser commercially available today is a device the size of a table with a $50,000 price tag. The lab researchers are said to have offered an alternative the size of a pinhead, which can reportedly operate at room temperatures and use a small battery as power supply...
