“…With side-pumping, not only longer fiber can be used to ensure relatively uniform distribution of upper-level inversion particles, the thermal problem can be better managed as well. Furthermore, some ring fiber lasers [7,8] can employ side-pumping coupler. For high power fiber lasers, the unique side-pumping method is used which is mastered by SPI Corp. (UK) and IPG Photonics Corp.…”

Obtaining sufficient pump power is an engineering challenge in scaling fiber laser toward high power. A sidepumping all-fiber coupler with the coupling efficiency of 90.1% and the coupling power of 144.7 W was reported. The anglepolished pumping fiber was fused with the double-clad main fiber by carbon dioxide laser. The core of double-clad fiber was not interrupted. Based on this side-pumping coupler, a fiber laser with flexible configuration was demonstrated. The output power and the slope efficiency of fiber laser was 102.5 W and 77.1%, respectively. This side-pumping fiber coupler was beneficial to investigate efficient and reliable high power fiber lasers and amplifiers.

A cost-effective fiber laser architecture is introduced in which the output seed pulse is stretched and then returned in the oscillator for an additional single-pass amplification without spectral broadening. It is implemented in an all-PM-fiber configuration based on a Mamyshev oscillator with a low repetition rate of 1 MHz. It features a linear oscillator bounded by two offset chirped fiber Bragg gratings accompanied by a third one acting as a pulse recycling filter. The latter tailors the pulse profile in amplitude and phase to seed femtosecond chirped-pulse amplification systems without additional pre-amplification nor pulse stretching. A single-pump prototype generating 200-nJ, 100-ps pulses compressible to 290 fs at 1030 nm and at 960 kHz is demonstrated. Furthermore, simulations show how this new oscillator architecture can provide tailored seed pulses with high enough spectral energy density and low enough nonlinear phase to generate sub-200 fs, 40 µJ, > 180 MW pulses from an all-fiber setup involving a single tapered-fiber power amplifier, without pulse picking.
