The InnoSlab laser design, already established for neodymium doped laser materials, was applied to ytterbium doped laser materials. Nearly transform limited sub-picosecond pulses at 400 W average power at room temperature and without using CPA technique have been achieved so far. This compact, diode-pumped Yb:YAG InnoSlab fs-osc...$28.00

Presented at ICALEO 2009
To observe excimer laser machining through enclosed thin liquid films and the effects thereof on debris control, new equipment was designed to contain a small control volume that can be supplied with an enclosed laminar 0.5 mm film of DI water to flow over the workpiece at a controlled flow rate. Using the same equipment, comparison with open laminar thin film...$28.00

The water jet-guided laser technology has found a broad range of applications in the micromachining field. Its principle is to focus a laser beam into a hair-thin, low-pressure water jet, onto the sample. This hybrid system prevents heat damage to the material by cooling the cutting edges in between the l...$28.00
