Abstract
We investigate synchronous first and second order pulsed Raman lasers that can achieve frequency spacing of up to 1000 cm−1 for CARS microscopy applications. In particular, we focus on analytical and numerical analysis of pulsed stability derived for Raman lasers by using dispersion-managed telecom fibers and pumping at near 1530 nm telecom wavelengths. We show the evolution of the first and second order Stokes signals at the output for different peak pump power and the net anomalous dispersion combinations. We determine the stability condition for dispersion-managed synchronous Raman lasers up to second order. The results show that the stable second order Raman Stokes pulses with 0.02 W to 0.1 W peak power and 1 ps to 2.1 ps pulse width can be achieved in proposed dispersion-managed systems.
