Optical bistability in side-mode injection locked dual-mode Fabry-Pérot laser diode

Side-mode transmission diagnosis of a multichannel selectable injection-locked Fabry-Perot Laser Diode with anti-reflection coated front facet.

Theory and experiments on the side-mode-suppression-ratio (SMSR) enhancement and the linewidth reduction of a Fabry-Perot laser diode (FPLD) side-mode-injection-locked by using another FPLD are demonstrated to realize its potential application as a DWDM transmitter source. The SMSR, the spectral linewidth and the linewidth enhancement factor are simulated to realize the limitation of the FPLD-F...

Optical bistability in diode-laser amplifiers and injection-locked laser diodes.

Static and dynamic properties of dispersive optical bistability (OH) in semiconductor lasers biased from below to above threshold have been investigated theoretically. The OH result is found to be varied continuously from below to above threshold with its maximum value located just above threshold; this result has been verified experimentally. A much faster switch-off of OH can be expected when...

Diode-pumped passively mode-locked Yb:Y3Ga5O12 laser.

We experimentally demonstrated femtosecond operation in a diode-pumped Yb:Y(3)Ga(5)O(12) laser for the first time, to the best of our knowledge. By using Gires-Tournois interferometer mirrors for dispersion compensation and a semiconductor saturable absorber mirror for passive mode locking, pulses with a duration as short as 245 fs at the central wavelength of 1045 nm have been produced at a re...

Tunable Dual-Wavelength Laser Scheme by Optical-Injection Fabry-Perot Laser Diode

Self-starting self-mode-locked femtosecond diode-pumped Cr:LiSAF laser.

We describe a diode-pumped Kerr-lens mode-locked Cr(3+):LiSrAlF(6) laser that produces 50 mW of 70-fs pulses in the 820-890-nm range when pumped by two red diodes of 400 mW each. By using a lower-transmission output coupler we have demonstrated for the first time to our knowledge a self-starting regime with an output power of 10 mW and 55-fs pulses.
