Fast-axis collimator(FAC)

The “Fast-Axis Collimator” lens is the first and most important optical component of high power diode laser systems. The large numeric aperture allows the collimation of the entire diode power with best beam quality. The lenses are manufactured from high-quality glass and have an acylindrical surface. The high transmission and the good collimation properties guarantee best beam transformation efficiency for diode lasers.

Slow-axis collimator (SAC)

The “Slow-Axis Collimator” lenses consist of a monolithic array of cylindrical lenses. The very low curvature deviation of the individual lenses of the array of 0.5 % ensures most efficient collimation of the light of all emitters of a laser bar.

Beam transformation systems (BTS)

The BTS shapes the extremely asymmetrical far-field distribution of the emitter light into an almost round profile, which is bundled to a symmetrical focus with the HOC.

The BTS-HOC is a simple and efficient system for coupling the light of all emitters of a high power diode laser bar into only one fiber. It consists of only two elements, the Beam Transformation System (BTS) and the Hybrid Optical Chip (HOC).

The collimator produces, from the light of a single emitter, a symmetrical beam with an almost round far-field profile. The collimator consists of a monolithic glass block with two opposite crossed cylindrical surfaces having different focal lengths, which collimate the light from the fast and slow axes. The element is suitable for light collimation of multimode emitters, single mode diodes and trapezoidal diodes. Passive assembly edges simplify the mounting.

Fiber couplers

The fiber coupler allows a direct diode fiber coupling of single emitters with only one lens element. The coupler consists of a monolithic glass block with two opposite crossed cylindrical surfaces and passive alignment edges. The light of the fast and slow axes is collimated by one cylindrical lense to produce a symmetrical focus.
