The StarFibre range of compact and robust fiber laser sources from Rofin-Baasel UK (Daventry, Northankts, UK; are available with a power range of 100 to 200W. A combination of high beam quality, choice of power, and pulsed or CW operational mode selection means that the StarFibre series lasers can be used for a broad spectrum of precision welding applications. Performance characteristics are enhanced by the low inertia scanning head, which enables high welding speeds to be achieved over a large processing field. An optional camera and coaxial illumination system enables viewing of the weld area via the scanning head. The small spot size and low heat input enable these lasers to produce precision welds on components such as batteries, fuel cells, sensors, electro-mechanical components, and medical components.

Vytek’s (Fitchburg, MA; ProtoScribe Laser Scribing System is intended for low to medium volume production of thin film photovoltaic (PV) panels. It generates scribes P1, P2, P3 plus edge deletion on panels as large as 60cm x 120cm. Protoscribe delivers a precise, shaped, stable laser spot that creates scribes with uniform depth and width, creates clean scribe edges, minimizes HAZ, eliminates hot spots that can damage underlying layers, and eliminates scalloping that can cause shunting.

The IndyStar from Coherent (Santa Clara, CA; incorporates the RoHS- Almeta excimer tube design, which delivers several billion pulses at 193 and 248 nm. This new ArF laser produces stabilized energies of 8 mJ/pulse at 193 nm and 12 mJ at 248 nm operation, at repetition rates up to 1 kHz with a small beam cross-section. The Indy-Star is a next-generation replacement for the ExciStar S-Industrial excimer laser.
