Balanced Receiver
Spectroscopic methods are sensitive to flucuations of
the output power of the laser system. A very powerful tool to overcome
power flucuations and noise contributions of the driving laser system is to use
a balanced receiver.
A concept for overcoming the
described power fluctuations is to compare instantaneously the original
power of the driving laser system with the laser power after passing the
absorption line. This is realized by a balanced receiver. Balanced
receivers consist in principle of two photo diodes and an internal differential
amplifier which compares the signal of both photodiodes. A typical setup is
described within out technical documents. 
Sacher Lasertechnik devloped an excellent
balanced receiver which eliminates almost all noise from the
spectroscopic analysis. This tool should not miss in any spectroscopy
laboratory. |
