About: High power laser pointers from BeamQ Lasers. Choose from Green lasers and red lasers for a variety of uses including military, astronomy, educational and medical use.

This guide is about how to use high power laser, especially the high power diode DPSS laser. These DPSS lasers are widely used in industrial and labs.

Step 1: Read the Laser Specifications

Read the laser specifications , labels or manuals carefully, you need to know the laser wavelength, laser output power, laser colors. For most of the lasers, you can get the color by reading the wavelength. Red 660nm, green, 532nm, blue 473nm, blue violet 445nm, violet 405nm, infrared 808nm.

Step 2: Find Out Laser Switch

Find out where is the laser switch or laser trigger. Make sure the laser is turned off before connecting the power supply.

Step 3: Connect TTL Modulation Line

If you need TTL laser module, connect the TTL line

Step 4: Laser Safety Goggles

Wearing laser safety goggles, according to the laser color. Different color lasers need different safety goggles.

Step 5: Point Laser Head Outside

Make sure you point the laser head outside, don't point the laser to you or other human.

Step 6: Turn on Laser Switch

Turn the laser on, for a visible laser, you can see the laser beam.

Red laser with methylene blue for only 5-10 minutes of exposure was quite effective.

The methylene blue for the laser at 650 nm and red light (unknown Wavelength) with methylene blue as a

dye produced free radical oxygen.

Blue light even though the laser light was limited proved for blue light CFL for long hours to inhibit the growth

of this bacteria which I am testing.

An issue was tide, some detergents that blocked light from entering the cells of the bacteria. Long term use of laser and light sources

may produce bio fim that may block wavelengths from being photo toxic in effect.

The tide filtered with small amounts of purple lamp worked for 15 hour exposure on bacteria. Nutrients were added for more rapid growth.

Control grew and high concentration of tide not filtered is an issue in growth. Light may not penetrate the cells.

Electrical pulses at 7500 volts 20 ma for 5-10 minute exposures produced RFI that may interfere with bacteria growth. This method is expensive

and requires electrical training. I may test with 12000 volts 30 ma.

All growth for blue laser and red non pulsed and pulsed usually killed or inhibited the growth of bacteria. Maybe this method is only effective for

specific types of non sporing bacteria.

Oh UV disinefectant lamp at 254 without dyes or chemcials was super effective at tempary killing biofilm forming bacteria.

This unknown bacillius bacteria can be killed but the spores (Survive) for the purple laser properties. This is probably true for red laser (Methylene blue) experements as well.

Here is more data on a purple laser line effecting growth of bacteria for 1 day. These unknown bacteria also tested positive for endospore bacteria. Rod gram positive bacteria.

bacteria and glucose. 15 min. Growth: Negative. Yes for growth 24 hours after.

Yellow marker dye in water with glucose and exposure level
15 minutes Growth: Negative. Yes.

Here is more info on the 12 kV, 30 ma jacob ladder experiments with bacteria culture.

12 kV 30 ma transformer jacob ladder exposure to bacteria
for 10 minutes Growth: Negative. 5.35 uT

12 kV 30 ma transformer jacob ladder exposure 5 minutes
growth: Positive. 5.35 uT.

Notice that growth for 5 minutes but not for 10 minutes occurred. This level is harmful 11 times the safe background EM field but I am no were near it when it operates.

Here is some more info on UV 254 nm light source. Some blue light is also given off which combines the sterilization effects.

dye: Growth in 20 hours: Positive. (Blocked UV light from passing into culture.)

Normal growth of unknown bacteria 1 hour No growth. (UV lamp

You should give info on Invisible lasers too. You cannot see the beam and requires a camera or such to see it!

No growth of bacteria with yellow marker dye. 650 nm laser-- max wavelength is around 495 nm for this dye. Perhaps the laser energy was converted into heat and this plus the laser at 180 mw exposure killed the bacteria?

Here is 18 min for one day testing to see if yellow marker dye plus laser at 160 mw would work. To kill friendly bacteria or not??

Blue light at 460 nm.

Lux = 54.3

Lux black lamp 460 lux.

54.3/460 lux *100% = 10% efficency. other materials can be lower like 1-5% in water.

Here is a picture of tonic water which has approx 83 mg quinine per L. So for 100 ml there is 0.83 mg quinine. Here is the picture.
