    I am also tinkering with an idea even if the emitter is larger but I have to wait for something to be quickly fabricated to see. Actually if this idea works, it will work with any diode.

    I will be back Later.

    Default Here we go again !!!

    Well...as the title sez...I am very puzzled at the reported results concerning the P73 ...so far. I do not have one yet....and am extremely interested in ANY information...from ANY member !!! Looks like I must get a P73 and check it out !!! Thanx !! BEAM

    ^Nice pic CDBeam lol..

    but..

    A Multi-emitter??

    I dont understand..

    Each diode has a single resonator cavity, multi-mode, yes, but multi-emitter? What do you mean ?

    Yea...I had a non-focus moment !!! Multi Mode is what I meant !! I was thinkin about about Emitter size and why the hell would they change the emitter size ???? BEAM

    well, if the increased emmiter size means that it can handle more abuse and we find that this is like the 445nm ones and can operate reasonably well above one watt, then maybe it is worth it to take the plunge and GRIN the damn thing. then, beam shaping will be much easier

    It is a good thing that it already is open can; makes the job easier

    Spot on Lanek,

    So shall I change the GB to be " Pre-fitted with Grin Lens "

    A GRIN !!! Micro manupilators...UV setting epoxy...Yikes...My hair is on fire !! So...Andy...How Much $$, How soon ?? I assume the GRIN will replace the Collimation lens....so...alignment between the LD and Colli just goes away !!! Fine with me !!! It was a PITA anyway !!

    Will additional C-lenses be required to do the final correction ?? I assume they will still be needed !...And just when I thought the G71 solution would apply to the P73 badboy !!! Well....Of course NOT !!!! Three steps forward...two steps back !!! Typical !!! !!! BEAM

    well, pending overdriveability of the diode and price of the GRINed solution, yes sir, go ahead and change the GB

    heh, is this news or what!!

    Overdriveability....I must remember this word !! We at Terrawatt Labs just refer to this as the " S & M " factor for a LD !! hahaha...Yikes....((( CRACK ))) " Thank you Sir...May I have another " mA !!!! BEAM
