染料激光器（Dye laser），是使用有机染料作为激光介质的激光，通常是一种液体溶液。相比气体的和固态的激光介质，染料激光器通常可以用于更广泛的波长范围内。由于有宽扩的带宽，使得它们特别适合于可调谐激光器和脉冲激光器。

染料激光器是由彼得·索罗金（Peter P. Sorokin）和弗里兹·彼得·薛弗（Fritz Peter Schäfer）（及其同事）在1966年分别独立发现的。

除了通常的液体状态，染料激光器也可以作为固态染料激光器（SSDL）。SSDL使用染料掺杂有机介质的作为增益介质。

A dye laser is a laser which uses an organic dye as the lasing medium, usually as a liquid solution. Compared to gases and most solid state lasing media, a dye can usually be used for a much wider range of wavelengths, often spanning 50 to 100 nanometers or more. The wide bandwidth makes them particularly suitable for tunable lasers and pulsed lasers. The dye rhodamine 6G, for example, can be tuned from 635 nm (orangish-red) to 560 nm (greenish-yellow), and produce pulses as short as 16 femtoseconds. Moreover, the dye can be replaced by another type in order to generate an even broader range of wavelengths with the same laser, from the near-infrared to the near-ultraviolet, although this usually requires replacing other optical components in the laser as well.
