Laser Diode Mode Hopping at Michael Theis blog

Laser Diode Mode Hopping. A semiconductor laser’s output spectrum depends strongly on case temperature and injection current. Achieving a stable laser power during hamr operation is extremely challenging and has been a key gating item in achieving high. Laser diodes can output continuous wave (cw) laser powers ranging from a few milliwatts for a single te mode laser diode to. This phenomenon is called “mode hopping.” sometimes, a laser diode is operated at such a state that two modes are equally close. For a typical gaalas diode, this is about 0.25 nm/°c, gradually combined with sudden steplike jumps (mode hopping). In automatic current control operation, precise temperature control yields the best stability for optical output power. In this application note, we show that mode hopping is directly correlated to noise in the total intensity, and that this noise is easily.
