摘 要:High-power quantum cascade lasers (λ =4.6 μm) working in continuous wave (cw) up to 90℃ are *** material was grown by solid-source molecular beam epitaxy and processed into narrow conventional ridge geometry without lateral *** cw output power of 850mW at 10℃ and more than 200mW at 90℃were obtained with threshold current densities of 1.34 and 2.47 kA/cm^(2),respectively,for a high-reflectivity-coated 12-μm-wide and 3-mm-long laser.
