"Test method for extinction ratio of LN, KDP and KDP electrooptic crystal"
Finally, it also analyzed the relationship between the input pump power and the probe optical power and its output power and output extinction ratio.
The extinction ratio changes with the operation current and temperature.
Due to the lasing effect, the peak modulation frequency of extinction ratio and chirp occur at the relaxation oscillation frequency.
A structure of the switch is given, which has an ideal extinction ratio and is characterized by its easy alignment and no strict confinement of the length along Z-axis.
It requires fast response speed, big extinction ratio, small fluctuation with endless reset or reset-free SOP control.
An instrument with three wavelengths for measuring the extinction ratio of laser crystal is described.
Test method for extinction ratio of Nd: YAG laser rods
The effects on the extinction ratio of double crystal electro-optic Q-switching were analyzed in this paper.
For the air-spaced polarising prism the air-gap thickness can be decreased infinitely to gain the large semi-field angle, or otherwise the extinction ratio is affected seri-ously.
As a result, the influence of signal light and bias current to the power and extinction ratio of converted light is studied in detail.
