He ripped off several people, including myself, then when we posted on alt.lasers to expose his scam, he came on and posted our personal information from eBay and claimed that we were all making up the same story. Many of his products are not as he says they are and many are just flat out lies and made up ads.
For Example:
HIGH POWER LASER DIODE SHG BLUE CRYSTAL BBO LBO KNBO3
HIGH POWER LASER DIODE SHG BLUE CRYSTAL BBO LBO KNBO3 - eBay Assemblies EM Devices, Electronic Components, Electrical Test Equipment, Business Industrial. (end time 06-Jul-09 13:02:16 AEST)
They just don't work that way, clear and simple, this ad is a lie, the picture is made up or is a photoshop. I have asked about this exact crystal, my boss, who received his PHD at Stanford dealing with, you guessed it, KNbO3, says himself that what is shown in the ad is pure bullshit, the power claims he is mentioning are pure bullshit, and on top of that, while not 100% accurate, the color of the dot in the picture is not what it should be.
8W HIGH POWER LASER DIODE DPSS PUMP MODULE UNIT 808nm
8W HIGH POWER LASER DIODE DPSS PUMP MODULE UNIT 808nm - eBay Assemblies EM Devices, Electronic Components, Electrical Test Equipment, Business Industrial. (end time 06-Jul-09 13:37:05 AEST)
This is a pump module from a Laser Export Q-Switched 355nm laser. It is good for ~4W peak power with a repetition rate of 200hz, not 8W CW as claimed. Additionally, there are no beam correction optics besides one lens in front of each diode and a final focusing lens once the two diodes are combined.
HIGH POWER YAG LASER SHG GREEN DPSS KTP CRYSTAL 3mm

These clearly say KTP Substrate on the box, meaning they are unfinished and uncoated. If he had actually fired a SSY-1 into it, he would have cracked the crystal and destroyed the surface.
