FiberMax ® Fiber Coupled Laser

Fiber Coupled Laser

Fiber Coupled Laser Component
Blue Sky Research is a world leading expert in precision ﬁbercoupling for a large range of laser diodes, from IR to violet .
Based on its proprietary technology, the FiberMax®
(FMXL) provides excellent coupling eﬃciency and stability ina cost-eﬀecJve package. The thermally stable design of theFMXL is highly reliable and ﬁeld-proven with hundreds ofthousands of units operaJng in demanding applicaJons.
Standard FiberMax® laser components are available for quick
delivery with common features: high performance laser
diodes coupled into a single mode PM ﬁber with an FC/PC
connector.

Advantages of Using Fiber
The unique properJes of opJcal ﬁbers reduce opJcal systemcomplexity and enables lower cost. System performance canbe opJmized while using cost eﬀecJve ﬁber for light relay
and beam shaping. A single mode ﬁber creates a near perfect
Gaussian beam without introducing aberraJons. In addiJon,
opJcal ﬁbers maintain beam poinJng tolerances throughout
temperature variaJons beTer than all tradiJonal opJcs,
enabling a robust and stable system performance over wide
operaJon condiJons.

Collimation Optics
Blue Sky Research oﬀers a miniature cylindrical collimator as an opJon for FiberMax® products. Thecylindrical 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. The cylindricalcollimator opJons have unique beam size and divergence speciﬁcaJons (e.g. M, N, P, Q) and are wavelength
dependent. Collimated beam requirements must be speciﬁed at Jme of purchase. OpJonal focus opJcs areavailable.

ACC and APC Opera5on

ACC (automaJc current control): Laser Diode driving current must be generated via a constant current
source for ACC operaJon. User can deﬁne current value relaJve to laser power output.
APC (automaJc power control): Laser power is detected via a photodiode inside laser housing. An error
signal is generated to adjust the LD current to lock the power to a user speciﬁed segng or preset value.
Based on applicaJon, customers choose to use either ACC or APC operaJon. Normally, ACC driving circuityprovides lower noise operaJon and APC circuitry provides beTer long-term stability. FiberMax® with B pinout can be directly used for both APC and ACC operaJon. F pin-out can only be used for ACC operaJon
unless an external photodiode is used.
