Cryogenically-cooled Ho:YAG laser in-band pumped by a Tm fibre laser [PDF]

, 2009
Scaling of laser power and brightness to meet the needs of ever-demanding applications is a demanding task which continues to preoccupy many within the laser community. In conventional 'bulk' solid-state lasers the main obstacle is heat generation in the

Vertical-external-cavity semiconductor lasers [PDF]

, 2004
Surface-emitting semiconductor lasers can make use of external cavities and optical pumping techniques to achieve a combination of high continuous-wave output power and near-diffraction-limited beam quality that is not matched by any other type of ...

All-optical intensity noise suppression for solid-state and semiconductor lasers

Journal of Telecommunications and Information Technology, 2005
This paper will report on a new all-optical technique of relative intensity noise (RIN) suppression for solidstate and semiconductor lasers. The new scheme we have used is based on an unbalanced Mach-Zehnder interferometer (UMZI), which is able to ...

Nanosecond Self-Q-Switching Nd:Luag Laser With High Repetition Rate

IEEE Photonics Journal, 2021
Numerical and experimental studies were investigated for the self-Q-switching Nd:LuAG laser which was achieved by the Kerr lens effect. By applying two output couplers of 6% and 1.4%, the shortest pulses of 193.4 ns and 5.1 ns were ...

Graphdiyne-Based All-Solid-State Passively Q-Switched Tm:YAP Laser at 2 μm

Nanomaterials, 2023
All-solid-state Tm lasers have a wider wavelength range and higher output power compared to other types of lasers. In this work, we demonstrate an all-solid-state, high repetition, Tm:YAP laser Q-switched by a graphdiyne (GDY) saturable absorber.

Continuous wave and modelocked femtosecond novel bulk glass lasers operating around 2000 nm [PDF]

, 2011
This thesis reports on the development of glass-based femtosecond laser sources around 2 µm wavelength. In order to be able to produce 2 µm radiation the dopants used were trivalent Thulium (Tm³⁺) and trivalent Holmium (Ho³⁺) that could be optically ...
