A red high-output semiconductor laser for DVD-RW with 240mW of optical power - the highest in the Industry
 |
Rohm has completed development of a high-output semiconductor laser with a maximum 16x capacity for DVD writing. |
The AV/PC market for DVD recorders, DVD-R/RW, and RAM is rapidly expanding. While DVD media will become indispensable for recording large volumes of data such as video, larger volumes of data will entail longer recording times.
Market trends are moving towards high-speed DVD-RW capability for easier use of PCs with built-in DVD-RW and DVD recorders that have built-in hard drives. The power required to write 1 bit's worth of data is equivalent to the strength of the laser optical output, so the higher the laser optical output is raised, the faster the writing time will be. Demand for higher output in semiconductor lasers from 2X to 16X is growing for faster DVD recording. The RLD65PZB5 high-output semiconductor laser developed by ROHM delivers 240mW of optical output, making possible a 16X maximum speed for DVD recording. In order to control the rise in current associated with greater output, ROHM has used an original element design. This has made it possible to deliver both high output and excellent heat characteristics.
Developing new elements with excellent heat characteristics has made it possible to include them on the standard 5.6f package that has a reputation for better results than previous models. ROHM's 5.6f standard laser diode package commands a high market share and has a high production supply capacity, and is therefore endowed with the advantage of being able to start mass production for a stable supply to customers and at a high level of quality.
The RLD65PZB5 high-output semiconductor laser has the following features:
| 1) | Po (optical output): 240mW |
| 2) | Rapid response: 2ns or faster (50% of previous speeds) |
| 3) | Low aspect ratio (divergence angle): 1.7 |
| 4) | 5.6f metal package (light-emitting point: 1.35 mm) |
Rohm will continue leading the marking with high-performance chips and advanced production technologies to meet a wide range of demand for set makers.
