Hybrid semiconductor master-oscillator power-amplifiers with more than 5 W optical output power

Semiconductor master-oscillator power-amplifiers (MOPAs) are versatile tools for various applications. We will present high-power (P > 5 W), high-coherence length (L-c > 100 m), small-sized (L <= 25 mm), hybrid semiconductor MOPAs at 920 nm, 976 nm, 1030 nm, 1064 nm, 1120 nm, and 1154 nm. We compare their performance to corresponding distributed Bragg reflector tapered laser and discuss strategies to extend the wavelength range.
