San Diego - Rohm Co. Ltd. has launched a 180-milliwatt infrared laser for 32x CD-rewritable drives that are said to take the stress of high power output without its facet being destroyed.
The RLD78PZW2 laser can stand more than 400 mW of stress, whereas conventional lasers are destroyed at less than 300-mW output power, according to a spokesman for the company.
The laser also boasts "kink-free," stable linearity. That is, the output power increases in proportion to input current. The linearity and the resistance to output-power stress provide a large margin for design flexibility, the spokesman pointed out.
The laser offers output power of 180 mW at pulsed operation; emission wave is within 779 nm to 789 nm. Threshold current is 30 mA and operating current stands at 120 mA.
The laser is packaged in a 5.6-mm-diameter metal can; one with a 3.5-mm diameter is planned.
Rohm will begin volume production this month. Samples are available now for $17 apiece. In July, the company rolled out a 150-mW device for 16x CD-RW drives.
