This year snowflakes come trapped in glass and are visible only with the help of polarized light. Single-pass welding of 1-mm thick, fused silica glass is enabled using the​​ BiBurst​​ function of the CARBIDE femtosecond laser​​ from Light Conversion. Adhesive-free bonding is interesting for various pharmaceutical, aerospace, and green and environment-friendly applications.

LHPG is a method used in industry and material research, notably for high melting point materials, because of its flexible and cost-effective fabrication of single crystal fibers. The laser beam is guided into a closed chamber, where it hits a reflaxicon that converts the laser beam to a hollow cylinder shape. The beam is then guided to a parabolic mirror that focuses the radiation over the pedestal source.​​ 

In practice, however, small thermal fluctuations lead to a variation of the fiber diameter. This can be overcome by using a stabilized laser source, such as Access Laser’s AL50ST, and by monitoring the melt zone.

CARBIDE from Light Conversion is an industrial-grade femtosecond laser system offering burst-in-burst capabilities for simultaneous GHz and MHz operation. This laser can output up to 80 W of average power, pulse energy of up to 800 μJ. CARBIDE can operate at a base repetition rate of up to 2 MHz. The laser can emit up to 10 pulses at MHz and 10 pulses at GHz burst, which is equivalent to an effective frequency of 100 MHz.

A state-of-the-art laser system with two optical parametric amplifiers (OPAs), including Light Conversion’s​​ award-winning ORPHEUS-MIR, was installed at Silicon Austria Labs (SAL), Austria’s top research center for electronic-based systems. This versatile combination of Light Conversion’s OPAs provides broadband pulses in the UV–MIR range with sub-100 fs pulse duration.

These parameters are ideal for sum-frequency spectroscopy and semiconductor characterization experiments.
