About Semiconductor Lasers
Semiconductor lasers use semiconductor gain medium, where optical gain is achieved by injecting current at an interband transition with high carrier density in the conduction band. They are compact in size and have low maintenance cost. The material often used in the semiconductor laser is gallium arsenide, and thus it is also known as a gallium arsenide laser. Semiconductor lasers are also used in new manufacturing processes such as micromachining. Lasers reduce the costs of end products by improving throughput and yield. The industrial segment spans a range of laser applications such as welding, cladding, metal cutting, and heat treating in segments ranging from automotive, gas, and appliance manufacturing to high-precision microelectronics fabrication and micro structuring in machine tool production.
Technavio’s analysts forecast the global semiconductor laser market to grow at a CAGR of 7.5% during the period 2016-2020.

The market is divided into the following segments based on geography:
Technavio Announces the Publication of its Research Report – Global Semiconductor Laser Market 2016-2020
Technavio recognizes the following companies as the key players in the global semiconductor laser market: Coherent, Novanta Group, Han’s Laser, Rofin-Sinar Technologies, and TRUMPF.
Other Prominent Vendors in the market are: Fanuc, GBOS Laser Technology, Lumenis, Laser Photonics, Quanta System, Active Fiber Systems, Advalue Photonics, Calmar Lase, Furukawa Electric, Hypertherm, Lumentum Operations, and Nufern.
Commenting on the report, an analyst from Technavio’s team said: “Increase in number of mergers and acquisitions will be a key trend for market growth. The global CO2 laser market has been consolidating, and this is expected to continue during the forecast period. Existing vendors are acquiring new firms to either enter the market or broaden their product portfolios. In 2012, Coherent entered an acquisition agreement with Innolight and Lumera Laser to strengthen its market presence. Thus, the increase in the number of M&A will drive the market's growth during the forecast period.”
According to the report, the growing acceptance of fiber lasers will be a key driver for market growth. Material processing involves chemical or mechanical steps for the manufacture of products in industries such as general manufacturing, automotive, heavy industry, electronics, and aerospace. Material processing applications include metal welding, plastic welding, brazing (mostly in automotive engineering), cutting of metals, and welding or cladding for the automobile, machine tooling, and medical sectors. The rigid machine architecture of other laser products sometimes creates an issue of field serviceability, leading to an increase in the cost of ownership. Fiber lasers have a modular design that enables simple field replacement of components in the case of machine failure. They are preferred over other lasers for materials below 5 mm in thickness as they provide better quality cut finishing at low cost.
Further, the report states that shortage in supply of rare-earth elements will be a challenge for the market. Fiber lasers contain dopants like ytterbium and erbium that are used to emit radiation from the pump light. These dopants are categorized as rare earth elements and are widely used in technological sectors such as lasers and energy, and industrial applications such as aerospace. These sectors have been facing a shortage in the supply of these elements in recent years. Some essential laser active dopants are neodymium, yttrium, ytterbium, and thulium.
