Direct Green Diode Lasers Mass-Produced
Laserprodukte GmbH of Rodgau, Germany, has begun volume production of direct green
(515 nm) diode lasers specifically for biotechnology applications. The devices
offer numerous advantages over conventional argon gas lasers and diode-pumped solid-state
lasers, the company said. With their direct analog modulation up to 500 MHz, they
need no optoacoustic modulator, resulting in smaller, more cost-effective devices.
They have greater power efficiency (the Luxx diode lasers have an optical output
power of 25 mW while consuming only 5 W), leading to a longer lifetime. They also
feature system readiness in less than two minutes. In the company’s Luxx and
Phoxx laser series, the new 515-nm diode laser will replace diode-pumped solid-state
lasers of the same wavelength.
