Abstract
We reported on a compact and efficient in-band pumped partially pumped slab (Innoslab) picosecond amplifier. A new method for mode-matching was demonstrated to simplify the amplifier design. Integrating the benefits of the in-band pumping technique and the excellent thermal management of the Innoslab amplifier design, a 105 W, 8.4 ps laser output was achieved with near-diffraction limited beam quality of and in the orthogonal directions.
