The educational kit CA-1230 is provided to train students in understanding of the laser diode pumped Nd:YAG laser with all its constants and properties. The kit teaches the students theory of Nd:YAG lasers including the discussion of rate equation model, steady state solution and dynamic behavior.
The kit uses a 450 mW laser diode with integrated TE-cooler and thermistor to control the laser temperature. All components to set up a complete laser diode pumped Nd:YAG laser with all necessary optics like crystal, mirrors, lenses and collimators are included. The provided versatile electronics controller combines the laser diode temperature and injection current control, a build in function generator to modulate the laser diode current and a photo diode amplifier converting the light signals for the measurements to be done:

• stability criterion of resonator
• dependence of pump wavelength on
  laser temperature and injection current
• absorption spectrum of Nd:YAG

Available options for extensions:

• components to upgrade the kit to
  'Optical Frequency Doubling' (CA-1231)

• components to upgrade the kit to
  'Short pulse generation by Active
  Q-switching' (CA-1232)

• components to upgrade the kit to
  'Short pulse generation by Passive
  Q-switching' (CA-1233)
