Superlum expands its product lines to include new free-space and fiber coupled SLD modules.
New low-cost SLD-380-MP-TO56
module is now available at 830 nm. The important advantage of this SLD is nearly elliptical far field pattern.
This allows direct replacement of laser diode modules in free space systems for reducing undesirable parasitic effects caused by laser diode temporal coherence,
New high-power multimode fiber pigtailed SLD modules SLD-M381, SLD-M341 and SLD-M531
are available at 840, 855 and 1065 nm center wavelengths.
These devices can be very helpful for low-speckle optical illumination for various applications in photonics where multimode fibers are used
for delivery of light. These SLDs are characterized by reduced sensitivity to optical feedback, compared with single mode SLDs.
A new model of Broadsweeper BS-930-1-HP with extended wavelength-tuning range.
Superlum is pleased to introduce a new model of a high-power wavelength-swept laser, the Broadsweeper BS-930-1-HP with
an extended wavelength-tuning range. The laser is built on the use of a quantum-confined SOA and a quasi-collinear AOTF
in an external fiber ring cavity. The device has demonstrated the full tuning range of up to 135 nm at the output power of
15 mW that is the best result ever shown for rapidly swept lasers in 880 – 1010 nm spectral range.
The device can sweep the emission wavelength with a sweep speed from 2 nm/s to 104 nm/s.
The laser offers the end-user different modes of operation — the manual sweep mode, automatic sweep mode, external sweep mode and
two-wavelength switching mode. The model provides high spectral and power stability of laser emission both in time and in temperature.
High spectral tuning accuracy and reproducibility together with strictly linear emission frequency sweep in time are ensured.
The device is equipped with a PM-fiber output that guarantees high values of PER of laser emission (> 20 dB).
Thanks to these advantages of the developed model over the existing BS-930-1, this new swept source can find
its place in a variety of applications requiring high-power laser emission together with rapid wavelength
tuning over a wide band of wavelengths covering 880 – 1010 nm. To the best of our knowledge, the new model of
the Broadsweeper considerably exceeds the existing analogues.

MOPA-SLD-850: The first commercial 850-nm SLD-based benchtop system emitting 50 mW from PM-fiber with a smooth, low-rippled optical spectrum.
Superlum is pleased to announce a new achievement in developing of high-power SLD-based light sources, namely,
the first commercial 850-nm SLD-based benchtop system emitting 50 mW from PM-fiber with a smooth, low-rippled optical spectrum.
The design is based on the "SLD MOPA" approach described in the corresponding application note. It is 100% PM-fiber-based and
provides stable output polarization with PER of 20 dB at the fiber output. In addition to very high optical power, there is another important
advantage of the "SLD MOPA" design, namely, its reduced sensitivity to optical feedback (see the application note for more details).
The instrument may be used in various applications requiring very-high-power and low-coherence single-transverse-mode light sources,
for example, Optical Coherence Tomography and white-light interferometry, spectroscopy, metrology, low-speckle optical illumination,
optical imaging and others.

Superlum demonstrates 50-mW SLD-based light sources with low sensitivity to optical feedback.
Superlum announces that it has achieved record-breaking power levels for SLD-based light sources.
The light sources utilize Master-Oscillator-Power-Amplifier (MOPA) configuration in which the light from a medium power master SLD is amplified by an appropriate semiconductor optical amplifier (SOA) of the same wavelength.
The use of MOPA system allowed us to demonstrate a light source at 840 nm with an output power of 50 mW ex SM-fiber and a spectrum width of 15 nm, while still having a negligible spectral ripple. An important advantage of the light source is its reduced sensitivity to optical feedback.
For more details on the new light sources, please refer to our new application note

close the gap between 770 – 1160 nm and 1270 – 1600 nm
spectral ranges of conventional SLD-based light sources.
Superlum introduces a new product line of light sources for OEMs, called
S-series Broadband Light Source Modules. These modules have the same
optical parameters as AC powered benchtop S-series Broadlighter devices, but were designed
for integration into optical coherence tomography (OCT) systems.
Medium power SLD-26-MP modules at 680 nm are divided into two subcategories,
based on output power. The first subcategory, the "MP1", corresponds to the former
MP category of SLD-26 modules. New modules with higher output power (up to 2 mW ex SM fiber) make up the second
subcategory, the "MP2". Free-space MP2 diodes have output power ranging from 3 mW (minimum) to 5 mW (maximum)
at +25 °C. This change allows our customers to choose medium power SLDs
that better meet the requirements of a particular application. It also provides
cost savings for customers looking for medium power SLDs at 680 nm.
The specifications were updated to reflect the change:
A variety of fiber coupled SLD modules in 1000 – 1100 nm spectral range are available now:

engineering quantities SLD modules rated from 0.5 mW to 2.5 mW ex
SM fiber output centered at 1480 nm, 1530 nm and 1560 nm. The device
ratings will be finally added to our Web Site by the end of July.
However,you can ask us on any detail right now.
SLD-26, 680 nm series diodes are now more powerful.
SM fiber output up to 20 mW, and free space outputs up to
40 mW are now available. Maximum residual spectral modulation depth
is now rated to 3%, twice less than before! In addition, devices
are now divided into different power categories, allowing our customers
to select devices that match their requirements better and safe
budget when very-high-outputs are not necessary. Considerbaly lower
priced, 3 mW free space, 1 mW ex fiber,
