This web page will be for nothing but spectra of lasers.
Ocean Optics USB2000 Spectrometer donated by P.L.
As of 10-10-07, I've been using a PC2000-ISA Spectrometer from Ocean Optics that I received several years ago, but that I didn't have a home for until now.
As of 03-08-07, I once again have the USB2000 spectrometer, enabling color spectra again.

LASERS (Pg. 1)
LASERS (Pg. 2)
LASERS (or "LAZERS" if you prefer):
Spectrographic analysis of the Blu-ray laser diode in the Blu-ray Laser Module (2) (the replacement unit); though the spectrometer's response band was narrowed to a range of 400nm to 408nm, and the color was turned off.
Spectral line halfwidth appears to be 1.9nm.
Spectrographic analysis of the Blu-ray laser diode in the Blu-ray Laser Module (2) (the replacement unit).
Wavelength (peak value) appears to be ~404.6nm, which is within specification for this laser diode.
Same as above (the replacement unit); though the spectrometer's
response band was narrowed to a range of 400nm to 410nm.
Spectral line halfwidth appears to be 1.9nm.
Spectrographic analysis of the 200mW Red Laser Module.
Spectrographic analysis of the 200mW Red Laser Module. though the spectrometer's response band was narrowed to a range of 650nm to 670nm.
Spectrographic analysis of the Blu-ray Violet Laser Module (2);
though the spectrometer's response band was narrowed to a range of 385nm to 435nm.
Spectrographic analysis of the 5mW 650nm Laser Module (2).
Same as above; spectrometer's response narrowed to a range of 645nm to 665nm.
The spectral line halfwidth is ~3.5nm.
Spectrographic analysis of the 5mW 650nm Laser Module.
Same as above; spectrometer's response narrowed to a range of 645nm to 665nm.
Remember, this instrument reads exactly 2.1nm long; the actual wavelength is 650.4nm
and the spectral line halfwidth is ~2.1nm.
Spectrographic analysis of the Blu-ray Violet Laser Module (2).
Spectrometer's response was widened to show this laser has a narrow emission line - as it should.
Spectrographic analysis of the laser diode in the Omega Airsport Gun w/ LED/Laser Sight.
Spectrographic analysis of the Blu-ray Violet Laser Module (2).
Same as above, but with spectrometer's response narrowed to a range of 385nm to 435nm.
Spectrographic analysis of the 5mW 532nm Green Beam Laser Module Pen.
Note the small NIR line from the pump diode.
Note too that I said "SMALL" here; this tells me that the IR filtering is adequate at worst.
Spectrographic analysis of the 635nm Red Weapons Laser Aimer.
Same as above; spectrometer's response narrowed to a range of 645nm to 655nm.
According to this, the peak wavelength is 651.6nm.
Spectrographic analysis of the green DPSS laser in the Laser Stars.
Spectrographic analysis of the True Green Laser Pen.
Note that there is no laser line at 808nm from the pump diode; this tells me that IR filtering is very good.
Spectrographic analysis of the ''Stick of Gum'' Laser Pointer, just above lasing threshold.
Spectrographic analysis of the Cupreous 50mW CR2 Green Laser Module.
Notice the 808nm NIR line from the pump diode is also *BARELY* visible here.
This tells me that the IR filtering is good, but it's not ***PERFECT***.
Spectrographic analysis of the laser in the 2-in-1 Laser/8 LED Light.
Spectrographic analysis of the laser in the Executive Style Pen w/Laser.
Spectrographic analysis of Extrema Keychain Green Laser Pointer.
Spectrographic analysis of Extrema Keychain Green Laser Pointer.
Same as above...{alarm sounds} {female computer voice} INPUT OVERLOAD!!!*
Let's try this again...same as above, but deliberately overloaded to check for the pump diode's 808nm laser line.
Actually, I did not need to overload the instrument at all, because no green
laser radiation was produced when this spectrum was taken.
Spectrographic analysis of a Pen-Style Laser Pointer.
Spectrographic analysis of a Blu-ray (Violet-Emitting) Laser Module (replacement, not original).
Spectrometer response was narrowed to 400nm to 415nm for this spectrum.
