Internal resonantly enhanced frequency doubling of continuous-wave fiber lasers
Internal resonantly enhanced frequency doubling of continuous-wave fiber lasers
In this Letter we describe a simple method for frequency doubling in high-power CW fiber lasers that offers the prospect of very high conversion efficiency and high power in the visible wavelength regime. Our approach is based on second harmonic generation in an enhancement resonator within the fiber laser cavity and does not require active cavity length stabilization. This technique has been applied to a cladding-pumped Yb-doped fiber laser to generate 19W of linearly polarized CW green output at 540nm, with excellent temporal stability for 90W of absorbed diode pump power at 975nm. The prospects for further improvement in performance with respect to conversion efficiency and output power are considered.

Abstract
In this Letter we describe a simple method for frequency doubling in high-power CW fiber lasers that offers the prospect of very high conversion efficiency and high power in the visible wavelength regime. Our approach is based on second harmonic generation in an enhancement resonator within the fiber laser cavity and does not require active cavity length stabilization. This technique has been applied to a cladding-pumped Yb-doped fiber laser to generate 19W of linearly polarized CW green output at 540nm, with excellent temporal stability for 90W of absorbed diode pump power at 975nm. The prospects for further improvement in performance with respect to conversion efficiency and output power are considered.
