    oh cool ! thanks Steve I currently have a pair of concave mirrors Sam gave me for red w/ROC @ 43MM ,and work great for most red diodes and hene , i made my first unit from an old Jodon external mirror HeNe cage. I am now re configuring it into much smaller package ........... its easy to swap out mirrors, and has a very fine focus adjustments.

    I can pay you in only gold holograms, you see im just a poor holographer that cant seem to leave the basement !


    Corning calls this laser a DFB laser "thru wet processing" it sounds so exciting!....... so it turns out theres a hologram in there dock

    im sorry i dont know how to bring this document posted by Pascal if you go to the linked thread and look at post #17 explains quite alot of info Thanks Pascal !

    Laser (the acronym derived from Light Amplification by Stimulated Emissions of Radiation) is a spectacular manifestation of this process. It is a source which emits a kind of light of unrivaled purity and intensity not found in any of the previously known sources of radiation. - Lasers & Non-Linear Optics, B.B. Laud.

    Are they 12.5 mm or 15 mm diameter mirrors on your Jodon? If its the usually Jodon 15 I can set you up REALLY GOOD.

    Then you can do a contact print for me of a certain grating master I really like. (Legal one, made it by accident one day, not a copy of some one elses grating)
    Makes exactly 4 orders and a primary beam, which looks KICKIN with a ion laser.

    I used to have access to and maintained a etalon stabilized UV argon with J Lock, and a green argon that was iodine locked. I miss severe coherence.

    Hey thanks Steve, up till now iv only used the concave mirrors sam gave me, my jodon frame uses the 12.5mm dia. The diameter size dosent matter as i have an edge grinder here ,if i switch to a plano/plano configuration, can I use my dichro mirrors ? Im itching to get that Corning G-1000 in my hands, any day now, any day now.............

    Yes i can replicate you Gratings no problem, DCG holograms w/200mw+ Coherent Sapphire 480 nm (yes its SLM)

    ok just a quick update on these fine lil lasers. After removing the G1000 from its fixture i hooked it up to a 5V 200ma power source and the heater to a 3VDC battery w/trimming resistor i adjusted the voltage slightly as i realised 3Vdc (full) was too much power. Low and behold the laser seemed to "lock in" when i trimmed some voltage. Now ive run the laser @ about 90mw for hours..... and it sure looks like its SLM ! hologram test tonight.thanks for all the info prorvided here .

    Care to share pin-outs?... Pretty-please, with a lumia-wheel on top?

    This is what I came up with earlier. Use at own risk.

    Pins from back left to right.
    1: Gnd
    2: LD +
    3: Gnd
    4: Heater 5Vdc

    As pictured in the pic in post 5

    Mod base freq :27.814 khz.
    About 2.5 volts.
    Heater pwm freq 285.878 khz.
    24% duty

    ok ive just shot three test holograms, the first two were banded quiet regularly (shot at different output powers), i then re-optimised the crystal heater and made sure diode was running full out............. A clean non banded hologram was then produced ! Telling me these ARE running Single Longitudal Mode ............

    I just shut the system off, ill now flip the switch "on" again and see if it maintains SLM.

    ok, Latest update. So im trying to compose a good dual driver,one for the diode and one for the heater. Any way in my half/ass way of testing......
    there was a brief open circut and then a reconnect ! Oops plop (i just heard $75 get flushed down the tiolet) ! Ok so it gave it life so others can shoot holograms with it's brothers!

    so now im starting on my #2 unit. i figured ill take this one a little slower and use ESD and all soldered wireing befor field testing ..........

    Before I really tear it apart, I figured you guys will appreacheat this.

    "first white light laser pointer" ?

    I simply removed the last turning mirror and the "hot"buttons on the left side, and with a little interior filing the beam exits nicely. If i were to do this again i was thinking about drilling a hole stright thru the unit just infront of the exit window and being able to then insert a pointer turning mirror and the beam would now exit thru the front window, and as a bonus if drilled out careful you should be able to still have a working projector (by removing then pointer mirror) .
