Abstract

A compact, robust, and inexpensive ﬁber-based source for coherent Raman imaging would beneﬁt both re-searchers and the clinical application of these imaging techniques. However, the relative intensity noise of ﬁber sources has precluded their use for stimulated Raman scattering microscopy without the use of electronic noise cancellation. A recently demonstrated ﬁber optical parametric oscillator was used to achieve high-quality images using coherent anti-Stokes Raman scattering microscopy, and demonstrated that the self-consistent nature of the oscillator aided low-noise frequency conversion. Thus, reducing the intensity noise on the ﬁber laser used to pump this device will be a critical step in creating a ﬁber-based source for stimulated Raman scattering microscopy. We will report the design and construction of high-energy dissipative soliton ﬁber lasers as a potential source of quiet picosecond pulses at 1 μm, along with application to pumping the optical parametric oscillator.
