• The discovery of new nonlinear optical (NLO) materials for coherent light generation in the deep‐ultraviolet (DUV, wavelength below 200 nm) region is essential for the development of laser technologies. Herein, we report a new material CsB4O6F (CBF), which combines the superior structural properties of two well‐known NLO materials, β‐BaB2O4 (BBO) and KBe2BO3F2 (KBBF). CBF exhibits excellent DUV optical properties including a short cutoff edge (155 nm), a large SHG response (≈1.9×KDP), and a suitable birefringence that enables frequency doubling down to 171.6 nm. Remarkably, CBF melts congruently and shows an improved growth habit. In addition, our rational design strategy will contribute to the discovery of DUV NLO materials. A beryllium‐free deep‐ultraviolet nonlinear optical material, CsB4O6F, combines the superior functional and structural properties of two established NLO materials, β‐BaB2O4 and KBe2BO3F2. CsB4O6F exhibits excellent DUV optical properties, a large SHG response, and a suitable birefringence that enables frequency doubling down to 171.6 nm.
