Conclusions
  • Saturated absorption is readily achievable in photonic bandgap fibers with power <10 mW.
  • We have characterized linewidth in terms of pressure and power.
  • Linewidth dominated by transit-time broadening.
    • larger-core photonic bandgap fibers desirable.
  • Counter-propagation prone to noise- careful polarization control required
  • We have got Satuation Power to be somewhere between
  •     25 to 50 mW.
  • We have also spliced the fiber outside the vacuum chamber and got very good splice.
