[IEEE 2019 Photonics North (PN) - Quebec City, QC, Canada (2019.5.21-2019.5.23)] 2019 Photonics North (PN) - Dual-wavelength Yb:YAP laser
摘要： Dual-wavelength operation of Yb:YAP laser with an intracavity birefringent filter (BRF) was demonstrated. By using a 1 mm-thick BRF, DW pairs with wavelength separation ranging from 1.8 nm up to 11.3 nm could be generated based on gain balancing provided by a single transmission peak of the filter. In this way, the wavelength separation was not limited by the available free spectral range of the filter.

摘要： Cascaded Raman fiber lasers (CRFLs) based on random distributed feedback (RDFB) enable high-power fiber lasers at arbitrary wavelength bands [1,2]. To enable further power scaling in these systems, we recently proposed the use of multiple low-power pump sources instead of a single high-power pump laser [3]. Simultaneous power combining and wavelength conversion of two independent Ytterbium (Yb) lasers operating at different wavelengths into a single lasing wavelength at 1.5μm was demonstrated [3]. However, the questions on whether this technique works for more than 2 pump inputs and with arbitrary wavelength separation were unanswered. Here, we demonstrate that the technique works for more than 2 pump inputs and also with wavelength separation between the pump varying from 5nm to 29nm.

High-efficiency, high-gain, all-fibered double-pass configuration for low-duty-cycle temporally shaped nanosecond pulse amplification
摘要： A high-gain fiber amplifier at 1053 nm with a double-pass configuration is proposed. Compared to the Faraday-based double-pass structures, the pump efficiency is almost doubled, and the optical signal-to-noise ratio is improved as well. The effects of fiber length and the insertion loss of elements between two passes on the efficiency are studied experimentally, which is meaningful for the optimization of double-pass amplifiers. Using the fibered polarized beam splitters allow for the orthogonal propagation of forward and the backward signals on the same polarization-maintaining fiber, the polarization mode dispersion in the amplifier is hence totally avoided. With this structure, over 50-dB gain is obtained at pump power of 800 mW for a 1053-nm, 1-Hz nanosecond pulse.
