Laser Optics and Fibers

Laser Mechanisms is the North American distributor of Optoskand's line of laser optics and fiber optic cables.


 

Fiber Optic Cables

QBH Fiber Optic Cable
The QBH Fiber Optic Cable is the standard fiber for high-power lasers. It is designed to withstand extreme levels of back-reflection from the workpiece; the internally water-cooled connectors absorb back-reflection up to 5 kW. Due to the conical guiding interface, installation is easy and accurate. Plug and play within 10 m.

 

RQB Fiber Optic Cable
An easy-handled fiber optic cable intended for more moderate power-levels and back-reflections. The RQB Fiber Optic Cable has the same conical interface and well-proven technology as the QBH, except there is no water-cooling. Plug and play within 10 m.

 

QD Fiber Optic Cable
The QD Fiber Optic Cable has recently gone through a successful design update. Still the connector fulfills the standard of the European Automotive Industry but it has been improved to handle even more power. In addition there is an integrated intelligence inside the connector. This makes the QD the top-of-the line fiber optic cable for high power lasers on the market.

 

Q5 Fiber Optic Cable
By using an interface compatible to the Trumpf LLK-B and then adding some Optoskand technology, including Quartz Block and Mode Stripper, you get the Q5 fiber optic cable. The power losses will be kept as low as for our other fiber optic cables.

 

QCS Fiber Optic Cable
The QCS Fiber Optic Cable is designed for high quality transmission and diffraction limited fiber lasers. The QCS concept is to cable an optical fiber with minimal impact on the beam quality. The QCS fiber optic cable then delivers a collimated beam from a convenient fiber connector.

 

SMA0.5 Fiber Optic Cables
The challenge with high-power fiber optics is not to handle the power within the core, but the power losses outside it. By moving the z-plane for a standard SMA905 forward and using the patented Optoskand modestripper technology - the SMA0.5 fiber optic cables are creating a new generation of high-power SMA-fibers.

 

Square Formed Fibers
Up until recently, the core geometry of fiber optics have almost exclusively been circular. With new geometrical possibilities, fiber optics is now not only guiding the laser beam to the workpiece but also actively forming the beam shape. Square formed fiber optics is specially aimed for high precision work where the beam shape is critical.

 


 

Incoupling Optics

Fiber to Fiber Optic Switch
The Fiber to Fiber Optic Switch (FFS) is built as a stand-alone unit sealed with a beam dump. With the FFS, one laser source can be time or energy shared between several fiber optic cables. The FFS has one fiber input and up to six fiber outputs. This opens up for flexible and cost-effective use of your laser source. The FFS is safety certified by BGFE.

 

Fiber to Fiber Coupling Unit
The Fiber to Fiber Coupling Unit (FFC) makes it possible to couple a laser beam from one fiber cable to another. When using an FFC there is no need to use longer fiber optic cables than necessary on exposed places, as for example in robot applications. The FFC is stable over time and loss in beam quality as well as power are minimized. The FFC is safety certified by BGFE and can be used as an eye-safe stand-alone unit.

 

Laser Beam Delivery Unit
The Laser Beam Delivery Unit (LBD) is designed to be built into a laser cabinet. The collimated beam from the laser is guided and focused into the output fiber optic cable. Up to three sealed LBD boxes can be mounted together in the laser, giving a maximum of six fiber outputs from one laser source. The outputs can be time switched or energy shared. The control of the system as well as the safety functions are integrated in the LBD unit.

 

Beam Delivery Modules
The Beam Delivery Modules (BDM) is a flexible modular system that delivers the laser beam from the laser source into the fiber. The modules are designed to be built into a laser cabinet. The BDM design is based on a modular concept with focusing modules, switching modules and a beam-bending module. Both time and energy sharing is possible. The BDM electronics are controlling the system as well as the safety functions.

 

Auto-Aligning Module
The Auto-Aligning Module (AAM) automatically optimizes the x-, y- and z-direction of the focusing lens in the fiber coupling unit (FCU) to get the laser beam into the core of an incoupled process fiber. By using the FFBD signals, given at the quartz block of the fiber, the AAM will scan the given FFBD values in the FCU and then automatically adjust the focusing lens to the best possible position.

 


 

External Optics

Collimating Units
Collimating units are used at the exit side of fiber optic cables. The function of this optics is to bring the transmitted laser light into a parallel beam. Different versions for different NA of the emitted laser light are available. The standard range of collimating units is prealigned, water-cooled and uses synthetic fused silica lenses to preserve the quality of your beam at high power levels.

 

Intermediate Optics
Between the collimating and the focusing unit the intermediate optics can be mounted. The aim of the intermediate optics is to modify the beam path or the focus shape. By using the Beam bending cube the collimated beam path will be turned 90 degrees. The Twin spot optics will divide the laser beam into two parts, resulting in two parallel focuses after the focusing unit.

 

Focusing Units
The focusing units bring the parallel beam from the collimating unit to a focused spot. The size of the spot and depth of focus is given by the combination of collimating and focusing optics. The focusing units exist both with a fixed focus position and as a z-adjustable unit, where the focal point position can be manually adjusted. The standard range of focusing units are prealigned and with synthetic fused silica optics for a precise result.

 

Process Adapters & Holders
Process adapters are mounted between the focusing optics and the workpiece. They support the process and protect the optics. For the prealigned product line there are also module holders. Making it easy to define the position of the focal point and make an optical system more stable.
