Abstract only attached.In this paper we outline a simple laser cavity which produces customised on-demand digitally controlled laser modes by replacing the end-mirror of the cavity with an electrically addressed reflective phase-only spatial light modulator as a digital addressed holographic end-mirror. We show that on-demand digitally controlled laser modes are possible by changing the phase and amplitude of the computer generated hologram in a form of a grey-scale image on the holographic mirror. We demonstrate that customised digitally controlled laser modes can be generated on-demand by switching to several different spatial modes in real-time with the first the ‘digital laser’.enLaser beam shapingLaser resonatorsSpatial light modulatorsSimple laser cavityDigitally controlled laser modesComputer generated hologramDigital control of laser modes with an intra-cavity spatial light modulatorConference PresentationNgcobo, S., Litvin, I., Burger, L., & Forbes, A.
