Abstract
Dilute nitride semiconductor disk lasers offer a convenient way of producing 570-650 nm radiation required in medicine and life science. These lasers can produce multi-watt powers with narrow spectra and compact footprints similar to solid state lasers. The advantage of using semiconductor gain materials is their ability to reach wavelengths that are not attainable by traditional solid state lasers. Other advantages include a wide tuning range and the possibility for electrical modulation. Here we demonstrate a narrow band (<30 MHz) yellow (589 nm) disk laser with 2.7 W output power. The gain mirror of the laser is optically pumped with an 808 nm diode laser. The emission wavelength of the laser can be tuned over several nanometers by tilting the filter inside the laser cavity.
