TIST develops low-cost DPSS laser device for ophthalmology, oncology

Scientists at the Toc-H Institute of Science and Technology (TIST; Kerala, India), following three years of research and development, have developed a diode-pumped solid-state (DPSS) Nd:YAG laser device that has utility in oncology and ophthalmology that they claim is low in cost.

Diode-pumped Nd:YAG lasers are extensively used in ophthalmology and oncology, but are typically quite expensive. In aesthetics, they are used for laser hair removal and treatment of minor vascular defects, such as spider veins on the face and legs. In dentistry, they are used for soft-tissue surgeries in the oral cavity.

The TIST research team is now working on the modalities to commercially launch the device in India. TIST principal Dr D. Vincent H. Wilson says that the Department of Science and Technology (DST; New Delhi, India) provided 49 lakhs in funding towards the three-year project, while TIST contributed 6 lakhs.
