Diode-Pumped Passively Mode-Locked Tm:
IEEE Photonics Journal, 2015 We report on a diode-pumped passively mode-locked picosecond Tm:CaGdAlO4 (Tm:CALGO) laser using a semiconductor saturable absorber mirror as the mode locker.

A Compact Self-Injection-Locked Narrow-Linewidth Diode Laser with Narrowband Dielectric Filter
Applied Sciences, 2023 The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth.

Integrated Phase-locked Laser Diodes at 1.55μm [PDF]
, 2017 Two types of integrated phased locked laser diodes operating at 1.55 μm were demonstrated, using either a distributed feedback laser seeding source or a self-locking multi-mode interference array.

Spectral Sidebands and Multi-Pulse Formation in Passively Mode Locked Lasers
, 2011 Pulse formation in passively mode locked lasers is often accompanied with dispersive waves that form of spectral sidebands due to spatial inhomogoneities in the laser cavity.

Theory of the ultrafast mode-locked GaN lasers in a large-signal regime
, 2011 Analytical theory of the high-power passively mode-locked laser with a slow absorber is developed. In distinguishing from previous treatment, our model is valid at pulse energies well exceeding the saturation energy of absorber.

Generation of microwave fields in cavities with laser-excited nonlinear media: competition between the second- and third-order optical nonlinearities [PDF]
, 2018 We discuss a scheme for the parametric amplification of the quantum fluctuations of the electromagnetic vacuum in a three-dimensional microwave resonator, and report the preliminary measurements to test its feasibility. In the present experimental scheme,

Self-mode-locking semiconductor disk laser
Optics Express, 2014 The development of mode-locked semiconductor disk lasers received striking attention in the last 14 years and there is still a vast potential of such pulsed lasers to be explored and exploited. While for more than one decade pulsed operation was strongly linked to the employment of a saturable absorber, self-mode-locking emerged recently as an ...
