Semiconductor laser chip sources are the most attractive coherent light sources available. This is due to their relative ruggedness, efficiency, affordable cost and small size. Semiconductor lasers are employed in a vast spectrum of applications from consumer electronics to photodynamic therapy. The color of radiation emitted by semiconductor lasers is governed by the material (the material bandgap) from which they are made. However, there is a limited set of suitable materials, which can be used in generating infrared laser radiation in semiconductors. Using those lasers in conjunction with frequency mixing elements can provide an alternative source to the conventional diode lasers. This novel source does not currently exist, would be in chip form, requires no alignment, and is electrically injected like electronic circuits. The technology that will be developed in this program will enable the realization of these novel lasers for the first time to provide coherent radiation in regions of the spectrum where no current sources exist using a commercially viable platform. The radiation will be vastly tuneable in comparison to other sources and is alignment free. These sources will provide a breakthrough for numerous applications including sensing, e.g. environmental, clinical analysis, life sciences, food monitoring, pharmaceutical, security and forensics, where they play a pivotal role.

半导体激光器芯片光源是最有吸引力的相干光源。这是由于它们相对坚固，效率，负担得起的成本和小尺寸。半导体激光器用于从消费电子产品到光动力疗法的广泛应用中。半导体激光器发出的辐射的颜色取决于制造它们的材料（材料带隙）。然而，有一组有限的合适材料，可用于在半导体中产生红外激光辐射。使用这些激光器结合混频元件可以提供传统二极管激光器的替代源。这种新的源目前还不存在，将以芯片形式存在，不需要对准，并且像电子电路一样被电注入。该计划将开发的技术将首次实现这些新型激光器，使用商业上可行的平台在没有电流源的光谱区域提供相干辐射。与其他源相比，辐射将是可极大地调谐的，并且是自由对准的。这些来源将为众多应用提供突破，包括传感，例如环境，临床分析，生命科学，食品监测，制药，安全和法医学，它们在其中发挥着关键作用。
