News from Daylight Solutions

Introducing the New Unicorn™ II Fixed-wavelength Lasers
Daylight Solutions has reinvented the fixed-wavelength laser.  The new Unicorn™ II series replaces our highly successful Unicorn™ line with improved pointing and wavelength stability.  At the time of manufacture, these lasers can be centered and locked down at any wavelength under the gain curve of one of the many chips we have developed.  For most wavelengths, the Unicorn™ II lasers ship with the capability to operate in both CW and pulsed modes.  Multi-spectral imaging, holography, and calibration procedures just got easier with economical access to the mid-IR.

Tuning Range Increase for Our CW-Pulsed Lasers

We have improved the quality of our laser chips and the precision of our manufacturing.  This translates into improved tuning specifications.  Many of our standard models can support broader tuning ranges than we have offered in the past (≥70 cm-1).  We now specify ≥120 cm-1 of tuning at 4.5 µm and ≥110 cm-1 at wavelengths in the 5-6 µm region.  Other tuning ranges have increased too. 

Narrowly Tunable Laser Series

Sometimes there is too much of a good thing.  Perhaps you need some tunability, but 120 cm-1 is more than necessary.  We now offer a series of “narrowly tunable” products.  The NT series of lasers offer between 30 and 40 cm-1 of tuning at an intermediate price point.  Pick the performance you need: fixed-wavelength, narrowly tunable, increased standard tunable, or don’t forget our Über Tuner™ line of broadly tunable systems offering up to 350 cm-1 in a single-chip package.

New Wavelengths

People are continuously finding new ways to use collimated, narrow-linewidth, high-power laser light in the mid-IR.  In turn, we constantly release new wavelengths to meet our customers’ expanding needs.  We recently shipped the shortest wavelength commercial QCL to date at 3.55 µm.  We also have coverage at 3.8 and 4.3 µm.  The 4.3 µm laser is available in a mode hop-free configuration and is centered right on the CO2 absorption band.  The figure below shows almost 50 cm-1 of mode hop-free tuning with the CO2 absorption lines peaking through from a partially purged beam line.  That’s the CO2 band center at about 2345 cm-1.

So you see, there is something new for everyone from Daylight Solutions: The Source for All Applications in the Mid-IR.  For further information, you can contact Chris Armacost, Ed Tochikubo, or myself.  Or visit us at FACSS, booth #37 at the Grand Sierra Resort in Reno, NV from 2 to 7 October 2011.  See you there.
