Red Diode Laser
Dec 2011
Laser Quantum Ltd.Request Info
STOCKPORT, England, Dec. 16, 2011 — Laser Quantum Ltd. has launched a lux red diode laser that delivers up to 1 W of power at 660 nm.

The company says that the high power is achieved with the high beam quality and long lifetimes expected from a diode-pumped solid-state laser. Features include a diffraction-limited TEM00 beam with M2 of <1.2, automatic power control, rms noise levels of 0.6% and power stability of 1%.

The compact and robust laser is based on diode-pumped optical technology. Applications include fluorescence imaging, spectroscopy, DNA sequencing, Raman spectroscopy and stimulated emission depletion nanoscopy.

The hermetically sealed laser offers >40,000 h mean time to failure, full RS-232 control, and a permanently aligned and zero-stress cavity. Beam diameter is 0.75 ±0.15 mm, bandwidth is ~30 GHz, beam divergence is <1.5 mrad, pointing stability is 10 μrad/°C, and polarization ratio is >100:1.

Polarization direction is horizontal, coherence length is <1 cm, beam angle is <2 mrad, and operating temperature is from 22 to 37 °C.

The instrument weighs 0.7 kg, and warm-up time is <15 min.
