View 01 - Three units side-by-side. The two on the left are air-cooled
units and the one on the right is a water-cooled slightly older unit with a
separate IR (1064 nm) and VIS (532 nm) fiber outputs.
View 02 - 4 kW switching power supply (230 VAC, 40 A primary input) and
air-to-water cooler unit.
View 03 - Controller board with many interlocks to deal with should you
wish to hot-rod this medical laser with the computer intact. (-;
View 04 - A look into the sun any one? Two pairs of glasses for me thank
you.
View 05 - Top view with cover off of the optics tray.
View 07 - Who say's optics loose little power? A close look at a couple
of the bending optics steering the beam through the optics tray.
View 08 - Another closeup of the 20+ W beam as it travels down stream
from the KTP and output coupler, pieces viewable here are low speed shutters.
View 09 - Front view of the unit with the hood up and face open, little
T-handle in white is a external wired power calibration unit.
View 10 - Side view of the cavity and steering and shutters.
View 11 - Lots of sensors and polarizer pieces. These units run the arc
lamp at 100% rated power all the time and they vary the output power with a
circular polarized disk which varies the polarization and thus
attenuates output power Note the purple glow on the optics holders the
camera picked up however your eye's would not until it's way to late...
(Huge IR power is way dangerous from an eyesight standpoint.)
View 18 - That's one bright beam even with all the lights on and look at
the scattered of the beam stop in the next room at distance it almost lights
up the other room's 7,500 square foot area.
View 19 - Far from a 100 micron clean room dust is ever present and very
visible when illuminated with this much power.
View 20 - Another top view of part of the cavity and optics tray. The
YAG and arc-lamp are under the cover with the High Voltage warning sign.
View 21 - Most of the optics tray.
Lower left is the output coupler for the 532 nm (VIS) and HR
for the 1064 nm (IR) of the Z-fold resonator and square black box is the
RF Q-switch (10 kHz). Upper right is the KTP oven and holder assembly optic
just above the Q-switch is the HR for both 1064 and 532 nm. Another HR
1064/532 nm for the cavity-end is just the other side of the cavity.
View 22 - Rear end of the cavity and the aforementioned 1064/532 HR.
View 23 - Unit powered up going through its self diagnosis.
View 24 - Footswitch that starts the laser operating.
View 25 - Rear cover with 40 A, 2 pole breaker and a 10 gauge 3 conductor
power cable. Water-cooled units would also have the water in and out ports
back here.
View 26 - A glimpse of green with the hood up and unit lasing at 532 and
1064 nm. This is way dangerous unless you have the best eye wear.
View 27 - Thick black plastic cover back on and ready for the next showing
