Lead-Free Lasers Outperform the Old Wave

"Ideal for applications such as low level laser therapy, medical imaging, industrial alignment, laser levelling and barcode scanning, Sanyo's new DL-6147-240 and DL-6147-040 lead-free laser diodes produce 40mW CW output power at 658nm, which is 10mW more output power than the DL-5147-042 series laser diodes which they replace in compliance with the RoHS Directive."
