In this we work demonstrate the output power amplification of the generated higher-order modes from a digital laser by using an extra-cavity Nd: YAG amplifier. The digital laser generates fundamental higher-order modes by encoding and displaying amplitude digital hologram mask on a phase-only spatial light modulator (SLM) that acts as an end-mirror of the laser resonator cavity. The amplifier was designed in such a manner that when higher-order modes enters the Nd:YAG amplifier they will experience higher gain which would translate to increase the power of the mode when it is transmitted through the amplifier.
