The INNOSLAB in-band pumping picosecond amplification laser system is studied with flake Nd: YVO4 crystal. 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. As a result, an average of 60.7 W, pulse width of 16.8 ps, repetition frequency of 20 MHz laser was achieved with optic to optic efficiency of 25.3%. The beam quality of 1.55 was obtained with 50 W output laser.
