- set_frequency(laser, value)[source]
Experimental!!! This is not the correct way to set the frequency! To use this function you need to set_grid_spacing = 1 before! The correct way would be to change the channel number! A warpper function: set_channel_frequency() can do this automatically for you.
This function sets the Laser Frequency in THz.
