We report a single-longitudinal-mode pulsed dye laser scheme in grazing incidence geometry. The points are to incorporate coaxial end-pumping and self-seeding into the conventional grazing incidence geometry termed the Littman scheme (Appl. Opt. 23 (1984) 4465). It is shown that the present scheme can considerably reduce the pump threshold and realize higher output power with better stability than the conventional Littman scheme.
