We present a detailed frequency noise characterization of an ultrafast diode-pumped solid-state laser operating at 25-GHz repetition rate. The laser is based on the gain material Er:Yb:glass and operates at a wavelength of 1.55 μm. Using a beating m

Optical transmission systems with terabit per second (Tbit s-1) single-channel line rates no longer seem to be too far-fetched. New services such as cloud computing, three-dimensional high-definition television and virtual-reality applications requir

We investigate power-scaling of green-diode-pumped Ti:Sapphire lasers in continuous-wave (CW) and mode-locked operation. In a first configuration with a total pump power of up to 2 W incident onto the crystal, we achieved a CW power of up to 440 mW a

To be competitive in laser micro machining, high throughput is an important aspect. One possibility to increase productivity is scaling up the ablation process i.e. linearly increasing the laser repetition rate together with the average power and the

The Physics and Engineering of Compact Quantum Dot-based Lasers for Biophotonics
The subject of this thesis is the investigation of novel technologies for mode-locking of diode-pumped, solid-state lasers. Novel saturable absorbers are used: quantum dots (QDs) and carbon nanotubes (CNTs), which both are low-dimensional nano-format

High precision laser micromachining requires an exact synchronization of the laser pulse train with the mechanical axes of the motion system to ensure for each single pulse a precise control of the laser spot position - on the target. For ultra short

We discuss challenges of the high-repetition-rate lasers and focus on quantum-dot SESAMs at 1550 nm. 10 GHz ERGO laser delivers 2 ps pulses when modelocked by InAs/GaAs QD SESAM with saturation fluence of 9 μJ/cm2.

We present amplitude noise characterization of a low-cost continuum source tunable from 800 to 1250 nm, with the pulse duration of 30 fs, and average output power up to 140 mW at 80 MHz pulse repetition rate. The system is based on a SESAM-modelocked

High throughput still represents a key factor for industrial use of ultrashort pulses in the field of surface structuring. Reliable systems with average powers up to 100 W are today available. It has already been proved that metals, especially steel
