STOCKPORT, England, Dec. 20, 2011 — For fluorescence imaging, optical tweezers and Raman spectroscopy applications, Laser Quantum Ltd. has unveiled the redesigned Ventus 532 green laser.

The family of products, launched in 2001 as midpower green lasers for use in scientific laboratories, has grown to include a power range from 50 mW to 1.5 W, with a number of laser heads. The redesign includes a more compact head and improvements in beam quality. Noise levels are down from 2% to 0.5% (0.15% for the higher powers), and power stability has been reduced from 2% to 0.4%. M2. Divergence and weight also have been improved.

The compact devices produce a diffraction-limited beam, offer a lifetime of >40,000-h mean time to failure, are hermetically sealed and have a permanently aligned cavity.

Offered with full RS-232 control, a zero-stress cavity and automatic power control, they produce a 1.5-mm TEM00 beam with divergence of 0.6 mrad and an M2 value of <1.1. They also deliver a bandwidth of 30 GHz and pointing stability of <2μrad.

Polarization ratio is >100:1, polarization direction is horizontal, and coherence length is ~1 cm. Beam angle is 1 mrad, warm-up time is 10 min, and operating temperature ranges from 10 to 40 ºC.

The Class 4 lasers weigh 0.75 kg.
