Lasers have become an increasingly crucial tool for multiple applications. By selecting the right tool and optimizing its parameters professionals can cover wide range of different technological tasks with optimum efficiency. Laser operating at the wavelength range of 2 μm is highly demanding due to its unique properties. Water absorption increases steadily from 1.2 to 2.9 μm, resulting in wavelengths of around 2 μm still belonging to the so-called “eye-safe” region – with water making up around 70% of corneal tissue. By falling within this region and still being at a suitable atmospheric window, lasers operating at the wavelength of 2 μm enable an entire range of applications and opportunities for free-space communication, remote detection & spectroscopic advances in environments that cannot be isolated from people.

Altechna solution for 2 μm applications

The development of new-generation optical components capable of managing today’s challenges is a complex process. It involves more than one discipline, ranging from material science to engineering. Altechna engineers have identified several technological bottlenecks of laser systems that work in the region around 2 μm and prepared a full industrial solution. High-quality optical components for laser resonators and delivery optics are now available in prototyping quantities, as well as for mass production.
