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 03-08-08, I once again have the USB2000 spectrometer, enabling color spectra again.
As of 09-19-09, I no longer have the PC2000-ISA; it was sold to prevent an eviction.
LASERS (or "LAZERS" if you prefer to be incorrect):

Spectrographic analysis of the Mystery Green Portable Laser. Note that there is no 808nm line from the pump diode; this tells me the unit is well-filtered.
Spectrographic analysis of the Mystery Green Portable Laser.
This shows the lack of IR emissions; the spectrometer's response narrowed to a band between 790nm and 820nm.
Spectrographic analysis of the green laser in the Reke 500RGB Stage Show Projector.
Spectrographic analysis of the green laser in the Reke 500RGB Stage Show Projector; spectrometer's response band narrowed to a range between 800nm and 850nm to capture the NIR laser line from the pump diode.
Please note that the amplitude is extremely low; it maxes out at approx. 85 vertical counts while most other spectra (including those of lasers) go to 4,096 vertical counts.
Spectrographic analysis of the Super Visible Green Beam Laser Module.
Spectrographic analysis of the Super Visible Green Beam Laser Module; spectrometer's response narrowed to a band between 781nm and 830nm to show NIR laser line from the pump diode.
NIR filtering is actually quite good; I had to "overload" the spectrometer by a significant degree just to get this "hump" to show. Here, let me show you with the following chart:
Spectrographic analysis of the Super Visible Green Beam Laser Module. See how much I had to overload the instrument to get that little piddling NIR laser line?
Spectrographic analysis of the laser in the Dapper Stage Laser Light Show.
Spectrographic analysis of the laser in the Dapper Stage Laser Light Show; spectrometer's response narrowed to a band between
800nm and 820nm and sensitivity was enhanced to show NIR emission from the pump diode.
IR filtering is actually quite good, but it is not absolutely, positively, 100% perfect.
Spectrographic analysis of the 5mW 532nm Green Beam Laser Module Pen (2)
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.

800nm and 820nm and sensitivity was enhanced to show NIR emission from the pump diode.

As you can see, none is detectable -- this shows that the IR filter in this laser is doing a fantastic job!!!
Spectrographic analysis of the green laser in the Portable Stage Lights; spectrometer's response narrowed to a band between 800nm and 820nm to pinpoint NIR laser line from pump diode. I had to seriously overload the spectrometer's inputs to find even this.
Spectrographic analysis of the green laser in the Portable Stage Lights; spectrometer's response widened to a band between 380nm and 820nm to show how much I had to overload the instrument to detect the 808nm laser line. See that broadband "emission" from ~550nm down to 380nm? That is caused by my overloading the input in effort to find that very tiny 808nm emission; the blue arrow points to the 808nm NIR emission from the pump diode.
So to put it briefly; the IR filter in this product is doing a SUPERB job!!!
Spectrographic analysis of the green laser in the Portable Stage Lights.
Spectrographic analysis of the green laser in the Portable Stage Lights; spectrometer's response narrowed to a band between 800nm and 820nm to pinpoint NIR laser line from pump diode -- which -- as you can see -- is completely filtered out. Yes, this is a very good thing -- you wouldn't want that stuff in your green beam!
