The first singlemode room temperature AlGaInP monolithically frequency-stabilised lasers are reported. Single frequency and single spatial mode operation is obtained using a second order diffraction grating to stabilise the operating wavelength. The device produced < 20mW CW with a differential efficiency of 0.18W/A and a sidemode suppression ratio of < 30dB.
