CIS Laser Information _____________________

The Center for Injectors and Sources has developed a myriad of lasers related applications to support the ever changing Jefferson Lab Physics Program.  These  include:

  • Gain switched diode laser and diode optical amplifier; combination of old and and new technology.
  • Pulsed light at GHz repetition rates.
  • Extremely reliable, low maintenance lasers.
  • A Mode locked Ti-Sapphire Laser for high current experiments using a novel active modelocking technique to obtain high power and GHz repetition rates.
  • Highly reliable pulsed fiber laser system

CIS has transferred this laser technology  to scientific colleagues at MAMI in Germany and Nagoya in Japan.
