PE-1500 Ruby Excited Lifetime & Spectroscopy
The invention of the Ruby Laser by Theodore Mayman in 1960 initiated the era of photonics technologies. This exciting experiment steps into the footmarks tracks of famous scientists and provides a comprehensive inside of fundamental quantum optics. Although the Ruby Laser did not find great application it is still the first Laser system which is introduced to students as first invented Laser. By means of a couple of simple components great physics can be demonstrated. Due to the broad absorption bands of the Ruby crystal peaking around 405 nm as well as 560 nm either blue or green emitting LED or laser diodes can be used as excitation source. However, here a blue LED is used which emits less than 5 mW at a wavelength of 460 nm.
