Abstract: An optically active waveguide laser 30 includes a multimode portion 126 for carrying more than one spatial mode at a predetermined wavelength chosen from a bandwidth including a pump wavelength 64 and the lasing wavelength 66. The multimode portion 126 has a first refractive index. A cladding portion 386 is proximate the multimode portion 126. A multimode grating 60, 56, or 62 is written on at least one section 26 of the multimode portion for reflecting the predetermined wavelength.
