    ... have you some absorption-rate images? -- AR-coating for 1064nm is not the same, as for 975nm ... had lenses "exploding" for less than 100nm "wrong" AR window and below 100 Watts on 5mm square transmitted power

    The 300w 976nm laser diode in the first post focused with air assist
    what thickness steel & stainless steel can cut ?

    ... this was a 200W-diode ... should be capable of slightly more than 1mm on air or around 2-3mm with oxygene ... the guy, where I have the 270W-diodes from, stated up to 2mm with air and above 3mm with oxygene ...

    Can be combined these diode lasers for higher power ?
    for example 5x200w=1kw

    ... yes, they can be combined -- but then the spot is slightly bigger too ... attached are some "laser-combinations"
