Abstract:
Broad-Tuning-Range, Stabilized, Diode-Laser System
There is a market for stabilized, tunable diodes--provided the principal advantages
of the diode laser (i.e., low cost, compactness, and high reliability) are maintained.
Recent advances in semiconductor manufacturing technology have led to an explosion
in diode laser availability across a wide wavelength range. This situation has created
a market opportunity for a plug-replaceable, stabilized diode laser device. The firm
has demonstrated tunable diode laser sources with high stability, compactness, and
low cost. By adding the ultrastable fine alignment unit required by replaceable source
lasers, the firm will extend the tuning range of a single system to cover the entire
accessible wavelength range from 0.63 microns to 2 microns and beyond. The objective
of Phase I will be to modify one of the stabilized prototypes to include the alignment
unit, to demonstrate that stabilized operation can be obtained for different diodes,
and to measure its vibration response spectrum in order to evaluate its stability
performance. Phase II will incorporate these technologies into a broadly tunable
package that can be used by NASA for a wide range of spectroscopic applications.
The commercial applications of this device will initially be in research. There are
many low-power spectroscopy applications that will use this source directly. For
high-power applications such as remote sensing of the atmosphere, this device can
be used to injection seed a Ti:sapphire laser.
