Abstract

We demonstrate a high-power, narrowband pulsed source at 390nm by two stages of frequency doubling in periodically poled MgO:LiNbO3 and periodically poled KTiOPO4 of an amplified, passively mode-locked fiber laser. With a frequency quadrupling efficiency of 5.5% and a 0.1nm bandwidth, the 250mW ultraviolet source is a suitable compact pump source for many entanglement-based quantum information processing tasks.

Schematic of pulsed UV source based on (a) passively mode-locked fiber laser, EDFA amplification, and two stages of SHG. (b) Detailed schematic of ring fiber laser. The non-PM fiber laser output is converted to a PM output using an inline fiber polarization splitter.

Fig. 2

Top panel: measured spectra of laser output and its SHG output at different EDFA power levels of (a) 1.3 W , (b) 3.4 W , and (c) 4.5 W . Dotted curve is the fiber laser output before EDFA. Bottom panel: measured intensity autocorrelation (IAC) for laser output at 1561.4 nm (filled triangles) and first SHG stage output at 780.7 nm (filled squares). Gaussian fits yield pulse widths (full width at half maximum) of 75 ps for fiber laser (dashed curve) and 49 ps for first SHG stage (solid curve). Data points for the fiber laser were collected only near the IAC peak due to limited range of the translation stage.
