Lightwave Electronics Series 126 NPRO Narrow Linewidth Ring Laser 1319nm

Description

This auction is for a very rare Lightwave Electronics Series 126 NPRO Single Frequency 1319nm Ring Laser.
This is a narrow linewidth ring laser with extremely long coherence length.
This laser currently dos NOT produce any output.  The fiber is kinked, see pictures.   Might need to be cleaved or removed entirely, but I am unsure if this is the problem.
The laser diode is drawing about 900ma but I measure no lasing output.  Perhaps you could remove the fiber assembly completely.
Laser control and diagnostics is accomplished by reading and applying voltages to the DB-15 connector on the rear of the laser head.
These include: measurement of laser diode temperature and crystal temperature, noise reduction control, thermal control of laser frequency, diode current adjustment.
There are 2 10 turn potentiometers on the back of the laser head for quick adjustment of laser diode current and crystal temperature.
The laser only requires a +/- 5V 5A DC power supply to operate.
Copy of the user manual is included.  This is a very comprehensive manual which covers operation, theory and control of the laser.
Please ask if you have any questions.
Buyer to pay shipping.
Thanks for looking!
NO EXPORT FOR THIS LASER, Thanks!
