Laser System Characteristics

Advantages of Using Fiber
The unique properties of optical fibers allow a reduction in
optical systems complexity and enable lower system cost.
System performance can be optimized while using cost effective
fiber for light relay and beam shaping. A single mode fibers canmaintain near perfect Gaussian beams without introducing
aberrations. In addition, optical fibers posses the ability tomaintain beam pointing and steering tolerances (<1urad/c)
throughout temperature variations better than all traditional
optics, enabling a robust and stable system performance overwide operation condition.

Collimation Optics and Feedback
Blue Sky Research offers two options for beam collimation; the Fiber Feedback Collimator or FFC, or theminiature cylinder collimator. The Fiber Feedback Collimator is a combination of an aspheric/doublet lenscollimator and an active laser power feedback system. The FiberTec module and FFC combination will
provide a stabilized optical output of < 0.5% (after 5min warm-up) and high polarization extinction ratio >23dB.
The cylindrical collimator is a miniature lens enclosure secured to the fiber pigtail’s connector and houses anaspheric or doublet lens which provides a specific collimated beam diameter and divergence. Both theFiber Feedback and Cylindrical collimator options have the same beam size and divergence specifications(e.g. M, N, P, Q). Collimated beam specifications must be specified at time of purchase. Please contact BlueSky Research for exact beam specifications at beam Diameter and divergence are LD (wavelengthdependent).

Electrical Connection and Operation of FiberTec & FiberDrive
Customer can choose one from two options of electricalconnection for FiberTec operation: 16 Pin or 8 wire ribbon. The
most advanced interface (16 Pin) uses two rows of 8 pins on thebottom of the unit. You can remotely access all functions
available in the FiberTec. FiberDrive product only has 8 wireribbon connection, as there is no TEC.
The Pin outs are shown above. When looking at the bottom of the module and the fiber existing from the left,
Pin #1 is in the upper left-hand corner, and Pin #16 is in the lower left-hand corner.

If you want to switch between ACC and APC modesof operation manually and you are using the 8 wireconfiguration, there is a physical jumper located inside
the FiberTec box (see right). Moving the jumper fromone position to the next changes the mode of operation. All FiberTec and FiberDrive modules without pins use
this jumper location for ACC and APC modes.

Evaluation Board

An optional Evaluation Board is available to quickly get FiberTec or FiberDrive modules (with a 16 Pininterface) up and running without the need to design/build a unique PCB. The evaluation board gives
users access to the optical output beam and all electrical connections including LD drive, control,monitoring, and protection circuits
The Evaluation Board has a built-in heat sink to help with thermal management, and four corner
posts to facilitate system mounting. All details to set up and operate FiberTec and evaluation board
are detailed in Application Note: FiberTec/FiberDrive Evaluation Board, Sept. 2019, V 3.0. User must
provide power supply for Laser Diodes, and TEC cooler if EB is controlling a FiberTec module.
