Function and applications

The light from a lasersiode is used to excite neodymium atoms in a Nd:YAG crystal.

Benefits

• The power emitted by the laser diode can be measured as a function of the supply current.
• The fluorescence spectrum of the Nd:YAG crystal is analysed and the main absorption lines of the Nd-Atoms are verified.
• Finally the half-life of the 4F3/2-level is estimated.
• With only a small number of additional components it is possible to build a Nd:YAG laser with this system.
