“…For the traditional end-pumped rod amplifier, the injected pumping power is limited by the heating effect. To obtain high power laser output, the multistage end-pumped amplifier or combination side-pump and end-pump amplifier is usually adopted, which leads to the use of many more components and worse beam quality [4][5][6][7]. Slab lasers and amplifiers use two large faces to dissipate heat resulting in better heat dissipation, which is more suitable for high power laser output.…”

We reported a compact and efficient Nd:YVO 4 partially end-pumped slab (Innoslab) nanosecond amplifier. The power of the seed was 5 W at a pulse repetition rate of 30 kHz with beam quality factors of M 2 < 1.3. A plane-plane cavity was used in the amplifier for high efficiency. With effective shaping of the seed laser, the output of 77 W was obtained under the pump power of 378 W without self-excitation. The optical to optical conversion efficiency was 23.8%, and the beam quality factors of M 2 were 1.52 and 1.32 in the horizontal direction and in the vertical direction, respectively.
