Focuslight Technologies produces dielectric coatings with IAD deposition. That includes anti-reflection coatings (from deep UV to the infrared), high reflectors, beam splitters and filters.

Focuslight Technologies offers laser diode bars:

• the water-cooled MCC09 with up to 500 W quasi-CW or 120 W CW at 808 nm or 940 nm

Focuslight Technologies produces a wide range of high power diode lasers, including both bare laser diodes and packaged lasers (modules). Free-space and fiber-coupled versions are available.

Focuslight Technologies offers packaged high-power conduction-cooled laser diode stacks for high duty cycle applications like laser hair removal:

• The Vsilk2 600 / Vsilk2 Pro 1000 offer 600 and 1000 W output power, respectively, at 808 nm.
• The Vsilk2 1200 / Vsilk2 Pro 2000 is available with output powers between 1 kW and 2 kW at 808 nm, with or without an integrated waveguide.
• The Vsilk2 1800 / Vsilk2 Pro 3000 generates 1.8 kW or 3 kW at 808 nm.

For low duty cycle applications like automotive LIDAR and 3D sensing, there is the BeamRazor ™Series – LE02 with >600 W peak power at 905 nm.

Focuslight Technologies has fiber couplers which allow one to couple the light from a single emitter or from multiple emitters into a single fiber with only one lens element. They consist of a monolithic glass block with two opposite crossed cylindrical surfaces and mounting surfaces. The light of the fast and slow axes is collimated by one cylindrical lens to produce an almost symmetrical focus.

Focuslight Technologies produces a wide range of high power diode lasers, including fiber-coupled modules, based on diode bars or on single emitters. Output powers between 15 W and 500 W and various emission wavelengths such as 808 nm, 980 nm are available.

Focuslight Technologies has laser diode collimator modules for high-power lasers, achieving the highest quality laser beams using only one optical element. They are pre-assembled and consist of FAC lens and SAC array or TEL array, with various assembly aids (e.g., side tabs or bottom tabs).

Focuslight Technologies produces a wide range of high power diode lasers, including packaged lasers (laser diode modules). Free-space emitting packaged diode stacks are available, also fiber-coupled modules, based on diode bars or on single emitters.

There are also specialized laser diode modules for medical and aesthetic applications like fat reduction and laser hair removal.

Focuslight Technologies produces a wide range of high power laser diodes, both as open packages or modules:

• single emitter components
• laser diode bars
• microchannel-cooled and conduction-cooled laser diode stacks
• emitter-based and bar-based fiber-coupled diode laser modules
• laser diode modules for medical and aesthetic applications like fat reduction and laser hair removal

The UV Line for Solid State Laser Lift-Off (LLO) from Focuslight Technologies has been successfully used for years in the lift-off field of OLEDs in the production of flexible mobile phone displays.

The development team at Focuslight has now enhanced the optical design far enough that the Gaussian profiles can be turned into a line with a length of up to 1000 mm and a width of 30 µm. The new features include significantly steeper edges and a wider intensity maximum. This allows an increased productivity by more than 30%. In addition, the sensitive OLEDs are subjected to lower thermal loads (lower ash value), yields are higher, and the OLED displays produced have a longer lifespan.

For the laser lift-off process of displays, we offer UV-Lines with different line lengths from 100 mm to 1000 mm. In addition to complete systems with long lines for integration into production, Focuslight also offers cost-effective systems with shorter lines, which can be used in advance in the process development.

Focuslight Technologies offers components for LIDAR systems, namely flash LIDAR transmitters and line beam LIDAR transmitters. We also have DMS illuminators.

Focuslight Technologies offers diode laser engines for hair removal as well as diode laser modules for fat reduction, as well as fiber-coupled diode lasers which are widely used for fluorescence imaging, surgery, and laser fluorescein angiography (LFA).

Focuslight offers micro-optics manufactured on wafers. The wafer-based production technology produces polished wafers up to 300 × 300 mm², making it possible to produce tens of thousands of lenses from high-grade glass and crystal in a single process step, with a consistently high level of quality. Combined with a significantly expanded production capacity, Focuslight’s highly productive and cost-efficient operations mean that the company can sustainably meet the growing global demand for optics in innovative photonics- and laser-based applications and technologies well into the future. The surface shape of every single lens of a micro-lens array can be individually designed to yield the best intensity distribution, while our high-precision manufacturing process on a wafer basis provides a high rate of repeatability and reproducibility. Combined with the choice of various glasses and an ISO9001 qualified coating, we can offer a wide spectrum of long-life micro-optics solutions.
