Sony Corp. announced that it is ready to join the blue-violet laser market through its diodes. The company hopes to gain market share through its enhanced monthly production capacity of 1.7 million units and low prices.

Sony will take on market leaders Nichia Corp. and Sharp. Corp. Sony said it hopes to gain market share through expanded production capacity and lower prices.

Sony said it is capable of fabricating 5 million blue-violet lasers a month if devices are low-power playback diodes. Current assembly capacity is limited to 1.7 million units a month but it can be expanded to meet market demand, a Sony spokesman said.

Nichia is currently ramping up its monthly capacity to 2 million by this fall. Sharp will double monthly capacity to 500,000 units by year's end.

Sony failure to establish volume production for blue-violet laser diodes limited the initial shipment of its Playstation 3. Since the introduction of PS3 last November, Sony has focused on internal demand. "Now we are ready for full-fledged marketing of the diodes," said the spokesman.

Sampling of recording diodes began this month. Diodes with a 170mW output power for 4x recording are already available. The SLD 3234VF comes in a 5.6mm diameter CAN package at a sample price of about $38. The SLD3234VFI with the same output power in 3.8mm package is priced at around $42.

Sony expects to add a higher power version with 240mW output power for 8x speed writing applications. Samples will be offered at the same price as the 170mW version. According to the company, its blue-violet laser diodes have achieved a lifetime of 10,000 hours.
