Coherent Inc. has released three new lasers that are designed to offer higher output power and increased throughput levels for solar cell manufacturing applications, including edge isolation, laser-grooved buried contacts and dielectric ablation.
Specifically, new AVIA lasers now deliver output power levels of 28 W at the short ultraviolet wavelength of 355 nm, and 45 W in the green at 532 nm. Each of these lasers represents the highest power level within its class, the company says. In addition, a new Paladin laser now delivers ultra-fast 80 MHz trains of picosecond pulses with power levels up to 16 W at 355 nm.
AVIA lasers have been qualified within numerous cell and panel manufacturing steps for both crystalline-silicon and thin-film production lines. Recently, the Paladin lasers have found complementary application adoption in which the further benefits of short pulsewidths provide cleaner material ablation at high speed, Coherent adds.
