Tested Dragon Lasers MGL-III-532-50 532nm Laser Head w/ PSU-III-FDA Power Supply
New see photos. Never put into use, tested only.
Tested works, see photos. We measured 70 mW of power with our power meter as shown in the photos (power meter not included in purchase). Laser was measured with a spectrometer, which gave a narrow line width spectra of about 533nm as seen in photo number four.
Dragon Lasers MGL-III-532-50 is a DPSS CW green laser built around a tight 532 ±1 nm line with 50 mW-class output; it’s the classic “clean 532” source for Raman excitation, alignment/collimation, interferometry/holography, fluorescence excitation, and general optics labs where spectral purity and beam quality matter more than raw watts. Factory spec highlights: TEM00 beam with M² < 1.2 (optional <1.1); ~1.2 mm beam diameter (1/e²) at the aperture; < 1.2 mrad full-angle divergence; linear polarization > 100:1; pointing stability < 0.05 mrad after warm-up; warm-up < 10 minutes; modulation support via TTL on/off (available ranges spanning 1 Hz to 30 kHz) plus analog modulation option; 10–35 °C operating range; and a rated ~10,000 hour expected lifetime with external PSU options (universal 90–264 VAC supply or 5 VDC OEM-style supply, depending on what’s included).
