Review of lasences 1W 545nm dpss laser

[Sowee7]

so a month ago I bought lasences 1w 545nm laser. It was pretty expensive compared to thier other products and it looked much bigger to. So it arrived last week as fedex had it stuck in china for some time. When i powered it on I was met with a very bright beam. It was even vissable in direct sunlight, the beam came out strait from the crystal. With a bad divergance of 40 mrad and tem01. Something interesting about this laser is that the OC mirror isn't coated on the crystal like most of there other products, instead the oc is at the top of the laser and can easily be removed

Is the beam profile round? Or is the beam truncated by the aperture?
