“…Currently, slab solid -state pulse lasers have been used in many fields, such as optical commun ication, laser printing, and 5G co mmunication technology, and have partially replaced the tradit ional rod-shaped and block-shaped solid-state pulse lasers. As an active ion, Nd 3+ ion has inherent advantages, including a long upper-level lifet ime, large absorption and emission cross sections, and convenience to obtain high power near-infrared laser [11], [12], [13], [14], [15], [16], [17]. However, the large emission cross -section of Nd:YVO4 crystal also brings high pulse repetition frequency in PQS operation, resulting in a decrease in single-pulse energy and peak power.…”

A slab laser based on Nd:CTGS crystal was reported for the first time. With a quasi-continuous wave semiconductor laser as the pump source, the maximum average output power reached 7.01 W, with a wavelength of 1064.5 nm, a single-pulse energy of 35 mJ, and a slope efficiency of 31%. Using a Cr 4+ :YAG crystal as the saturable absorber, the maximum average output power was 2.52 W, corresponding to a singlepulse energy of 1.26 mJ, a pulse duration of 37.2 ns, and a peak power reaches 33.9 kW. This work provides a good way to obtain pulsed slab lasers with simple structure and excellent performance, which are expected to be utilized in many fields like the photovoltaic industry, glass processing, tool manufacturing, mechanical engineering, and scientific research.
