With the product announcement of the new diode laser series "BluePhoton 488", Omicron is setting trends in the 488 nm wave length. Particularly for biotechnological applications, the new product family of the laser specialist is the first choice. In comparison with traditional argon gas lasers and DPSS lasers, the "BluePhoton 488" offers numerous advantages: Through the extremely fast direct analog modulation capability up to 350 MHz, there is no longer any need to use opto-acoustic modulators. As a result, the Omicron diode lasers with 488 nm diodes are smaller and more cost-effective. In addition, with a power of 20 mW, they are characterized by improved efficiency in power consumption and have a longer life time. A significant feature of the Omicron diode laser in the new wave length is the system operational-readiness in under two minutes. Furthermore, the astigmatism is compensated by the use of the innovative Omicron optics. This archives not only a round beam with a diameter of approximately one millimeter 1/e2 but also an absolutely round focus.

The use of typical laser components from Omicron products together with the 488nm wavelength produces sensational new possibilities. In combination with the spectacular "Deepstar" from Omicron, a diode laser with almost infinite modulation depth, the use of 488 nm diodes produces unrivalled results. In the Deepstar version, the "BluePhoton 488" indicates a bright/dark ratio of more than 2.5 million to one in the modulation state.

Due to an excellent temperature stability of 0.01? K and the use of the Omicron high-precision electronics, the "BluePhoton 488" gives a convincing performance with an extreme noise reduction of less than 0.1 percent (RMS) and a power fluctuation of less than 0.5 percent over 48 hours.

The modular principle of the laser heads of the LDM series also offers further possibilities for customer-specific adaptation, such as single-mode fiber coupling with an efficiency of up to 75 percent, collimation for 0.5 to 15 millimeters beam diameter, focussing objective to under one micrometer and a lot more.
