1.5 GHz picosecond pulse generation from a monolithic waveguide laser with a graphene-film saturable output coupler.

چکیده
We fabricate a saturable absorber mirror by coating a graphene- film on an output coupler mirror. This is then used to obtain Q-switched mode-locking from a diode-pumped linear cavity channel waveguide laser inscribed in Ytterbium-doped Bismuthate Glass. The laser produces 1.06 ps pulses at ~1039 nm, with a 1.5 GHz repetition rate, 48% slope efficiency and 202 mW average output power. This performance is due to the combination of the graphene saturable absorber and the high quality optical waveguides in the laser glass.

11-GHz waveguide Nd:YAG laser CW mode-locked with single-layer graphene
We report stable, passive, continuous-wave (CW) mode-locking of a compact diode-pumped waveguide Nd:YAG laser with a single-layer graphene saturable absorber. The depressed cladding waveguide in the Nd:YAG crystal is fabricated with an ultrafast laser inscription method. The saturable absorber is formed by direct deposition of CVD single-layer graphene on the output coupler. The few millimeter-...

Sub-picosecond optical pulses have been successfully generated using a novel monolithic passive colliding pulse mode-locked (CPM)l semiconductor multiple quantum-well (MQW) laser. Transform-limited pulse width of 830 femto-seconds is achieved at a wavelength of 1.5pm and a repetition rate of 80 GHz. The measured timebandwidth product is 0.31. A record high repetition rate of 350 GHz is also dem...

This paper deals with the experimental results of a xenon flash-lamp pumped passively Q-switched Nd:YAG laser using Cr4+:YAG saturable absorber. The need of a laser cavity to be integrated into a time-of-flight laser range finder is of great interest as an experimental investigation of several laser resonators. Two types of laser resonator, with different lengths, have been studied: the flat-fl...
