    Review of lasences 1W 545nm dpss laser

    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...

    Nd:GdCOB lasers

    so recently i got a few Nd:GdCOB crystals with hr and oc mirrors coated on the crystal. Nd:GdCOB is a very interesting crystal as it is self frequency doubling so it doesn't need an intracavity doubling crystal. also it can be very efficient (up to 20 percent efficient from what ive read). my...

    Yellow laser diodes might become real

    so recently I found 2 articles on yellow laser diodes at 560nm and 565nm. here is the link to the 565 one https://www.photonics.com/AMP/AMP_Article.aspx?AID=13986 Also i saw a company selling a joint diode laser. Could this mean yellow/yellow-green diodes are becoming a thing?
