I am Jimmy and I am a laser enthusiast. I dreamed to have a high-powered blue laser pointer since I saw someone used it to burn match one day. There is nothing can be excited that dream comes true, thanks my dearest friend Jason, the gift he sent me is a 500mW blue laser pointer today.
He kept the secret all the time. When I received a parcel from FedEx courier, I was curious what was inside and noticed it was sent from Laser To, Hongkong,but I had never bought things there and no friends there, either.
I opened it in a hurry and dare not to believe my eyes as soon as I saw it was my dreamed thing, a laser pointer. Then I can’t help shouting, OH MY GOD, it was 500mW blue laser pointer. After putting batteries inside it, I turned on it at once, cool, marvelous blue beam, to be honest, I don't think there are words to describe its beauty.
When I was thinking who sent me such big gift, my phone ring, it was Jason, my best friend.
Below is its Technical Parameters I copied from Laser To’s website,
Name Blue Laser Pointer
Wavelength 445nm
Output power 500mW
Laser class IIIB
Transverse mode TE00
Range in darkness (m) 300-8000m
M2 factor <1.2
Beam divergence, full angle (mrad) <3.0
Beam Diameter at Aperture (mm) <2.5
Spectral Line width (nm) <0.1
Polarization Ratio >100:1
Warm-up Time (minutes) <0.5
Operation Temperature (℃) 10～30
Storage Temperature(℃) -10～+50
Housing material Aluminum
Expected Lifetime (hours) 8000
Laser Head Dimensions(D×L, mm) Φ38mm×205mm
Cooling System metal heat sink
Operating voltage(VDC) 2×16340 batteries
Warranty time One Year
It is as big as a medium flashlight, a little bit heavy maybe because it is made of Aluminum.
Nearly forget the most excited experiment, burning match. Both of us wearing laser safety goggles, and found a blackhead match first, handed it about 10cm away from laser pointer, and turn on the laser pointer carefully, you know what, the match was fired within second. Then we moved it a little bit far away, about 50cm, the match was light in about 5 seconds. Remove about 1 meters, the time is longer, 15 seconds. Then we used it to pop balloon, cut tape and , it is a small case to it.
Here, I would like to share with you guys who need laser pointer for burning experiments. Blue laser pointer is the best one for burning experiments comparing with green and red in the same output power, as its wavelength is the shortest among them, and shorter wavelength is more readily absorbed. And black head match is much easier to light as black can absorb heat better than other colors.
Thanks Jason again for sending this magic match 500mW Blue Laser Pointer from Laser To.com.
