A method of frequency and mode stabilizing a tuneable laser, wherein one or more measurable magnitudes is/are measured, wherein the laser has been characterized with respect to a number of operation points, and wherein the values of the measurable magnitude or magnitudes are stored in a microprocessor or corresponding device. The invention is characterized by causing the values of one or more of the measurable magnitudes to be non-extreme values; storing the values of such non-extreme values as a quotient where the numerator is the derivative of a measurable magnitude deltaY with respect to a control current deltaI to one laser section, and where the denominator is the derivative of another measurable magnitude deltaZ with respect to said control current deltaI; and using the stored values to control the laser to a desired operation point. |
