High performance, cost effective alternative to 488nm argon ion lasers for biomedical instrumentation and semiconductor metrology
Blue Sky Research, a manufacturer of semiconductor lasers, laser systems and components, has announced that it is accepting orders for its Chromalase 488 blue laser.
This latest release complements Blue Sky's existing Chromalase product line of 635nm and 405nm high stability, free space lasers.
The Chromalase 488 is a semiconductor frequency-doubled 488nm laser that delivers 20mW output power with superior beam pointing and power stability in a single, compact assembly.
In addition to superior beam pointing accuracy, the Chromalase 488 requires only 12W input power, making it over 100 times more efficient than a 1.5Kw air-cooled Ar ion laser.
Utilising a high reliability telecom grade 980nm pump laser and a single passive SHG (second harmonic generation) crystal, the Chromalase 488 generates more than 20mW of 488nm output power and requires no external power conditioning, control boxes, or cooling fans.
The laser system is designed to operate from 5VDC, and includes a thermoelectric cooler and drive-control electronics.
Output power is variable and a DB9 electrical connector allows users to remotely control the laser.
The Chromalase 488 is a very compact, single-unit assembly measuring 145mm x 82mm x 33mm.
The required volume is 85% less than comparable argon ion lasers.
"The Chromalase 488 blue laser is a remarkable improvement over conventional 488nm Ar ion lasers for many applications, especially in terms of beam pointing stability over temperature," said Chris Gladding, president and CEO of Blue Sky Research.
"This product is designed to meet the requirements of demanding applications, including biomedical and analytical instrumentation, although it is equally suitable to semiconductor metrology."
