ABSTRACT
Continuous control of coherence length is realized in the output power region of 3–5 mW by changing the current flowing into the loss region of separately pumped (AlGa)As lasers. The controllable saturable absorption makes lasing spectra multimode and broadens the linewidth of an individual laser mode up to 2.5 Å through self-pulsation. The threshold current of the laser is 60–80 mA. The lasing wavelength is around 780 nm.
