Here’s our pick of the most exciting new products to make their debut at this year’s show.
• Coherent claims to have released the world's most powerful diode-pumped green laser that emits a continuous wave TEM00 beam. The Verdi-18 is said to deliver 18 W at 532 nm with an optical noise of less than 0.04% rms making it suitable for both materials processing and scientific applications.
Having acquired Positive Light last year, Coherent has also released a femtosecond laser system based on a regenerative amplifier. Called the Libra, the system emits 1W of 800 nm light at repetition rates of 1 or 5 kHz. The system can also pump multiple optical parametric amplifiers, and is tunable from the deep UV to the mid-infrared.
• Cobolt of Sweden has developed an optical module that emits a single beam containing both 491 and 532 nm light, at 20 mW and 50 mW respectively. The company claims its Dual Calypso system is an ideal replacement for argon-ion lasers used to perform laser-induced fluorescence.
• JPSA Laser says its IX-100 miniature UV laser can micromachine holes in materials such as polymers, glass, quartz and silicon with a precision approaching 1 micron. Designed for laboratory and low-volume use, the IX-100 emits 35 mJ, 248 nm pulses at a repetition rate of 300 Hz. According to JPSA, the product can be tuned to operate at 193nm by interchanging a premix gas bottle and the beam delivery optics.
• Elliot Scientific is selling an optical tweezer system that is the brainchild of researchers Kishan Dholakia and Michael MacDonald from St Andrews University, UK. The E 3100 contains a class 1 red laser diode, a 100x objective lens and a color CCD camera. The system can manipulate cells via a precision XY stage and perform XYZ trapping.
• Xenics of Belgium has released an InGaAs linear imaging array that is sensitive between 0.9 and 2.5 microns. With a resolution of up to 512 pixels, the company says that images can be captured at speeds up to 10 000 lines per second or at pixel rates of 2.5 MHz. According to Xenics, integration times can be as short as 1 microsecond which makes the product ideal for reflectance spectroscopy measurements.
• Femto Lasers of Austria has developed a Ti:sapphire oscillator that produces sub 50 fs, 80 nJ pulses and operates at a repetition rate of 10MHz. The FemtoScource scientific XL has a footprint of 900 x 450 mm, which includes the oscillator itself, the pump laser and the beam alignment optics.
