摘要
Holmium fibre lasers are required for remote sensing, LIDAR and some medical applications [1]. In addition, pulsed Holmium fibre lasers also offer an attractive power scalable alternative to Ho:YAG and Ho:YLF lasers for pumping mid-infrared optical parametric oscillators (OPOs). In these applications it is necessary to operate at a high peak power (u003e20 kW) with minimal spectral broadening (u003c2 nm bandwidth) [2]. This is challenging due to the onset of nonlinear effects such as modulation instability (MI) and stimulated Brillouin scattering (SBS).
