Researchers use frequency conversion to create a more practical, high-power femtosecond yellow laser
Researchers have developed a new compact and ultrafast, high-power yellow laser. The tunable laser exhibits excellent beam quality and helps fill the need for a practical yellow light source emitting ultrafast pulses of light.
“The yellow-orange spectral range is highly absorbed by hemoglobin in the blood, making lasers with these wavelengths particularly useful for biomedical applications, dermatology treatments and eye surgery,” said research team member Anirban Ghosh from the Photonic Sciences Lab at the Physical Research Laboratory in India. “A femtosecond, tunable yellow laser source might one day offer medical treatments that produce less thermal damage and are more selective.”
