Subject: Frequency stabilization of 1 micron source 

The schematic of the homodyne configuration is shown below.

Following are the list of components

Item Quantity Availability Part number  Remarks
Laser (NPRO) 1 Yes    
Couplers (50/50) 5 3 No's FOSC-2-64-50-L-1-H64F-2 Fiber type : Hi1060 Flex fiber
Delay fiber  two loops of 80 m Yes PM 980

 

One set of fiber is now kept along the arm of the interferometer

InGaAs PD (BW > 100 MHz) 4 Yes NF1611

Fiber coupled (3 No's)

Free space ( 2 No's)

SR560 3 Yes    
  • The fiber mismatch between the couplers and the delay fiber could affect the coupling efficiency
