Not temperature stabilized pulsed laser diode and all fibre power amplifier

摘要

Laser light (» L ) within a spectrum range is generated (51 g ) and filtered (29 g ). Thereby the spectral location of the filter characteristic (» F ) is shifted in a controlled manner (60) to establish a desired characteristic of output laser light as for considering a temperature depended shift (”Ñ) of the spectrum range generated by the laser source (51 g ).
