why dye lasers are also known as tunable lasers

The most useful feature of dye lasers is their tunability.  The tunability means that the lasing wavelength for a dye may be varied over a wide range.  Due  to this   reason, dye lasers are also called tunable lasers. Tuning over … Continue reading

Dye laser and its construction

Dye lasers use liquid organic dyes. These organic dyes are dissolved in solvents like water, ethyl  alcohol, methanol. The most widely used dye is rhodamine-6G, also known as Xanthene dye. These lasers are discovered by Sorokin and his colleagues. Dye … Continue reading

Output, use and disdavantages of semiconductor laser

Output of semiconductor laser: The output powers of about 10mW are achieved in continuous wave operation and in pulsed opration the peak power runs to 100W. It has output wavelength from 8200 to 9000 angstroms. So the wavelength of semiconductor … Continue reading
