    Make DPSS ruby laser worked!

    You can buy ruby easily, but it must be cut to small part and coated. It may cost much

    about 694nm,perhaps 694.3nm

    Make DPSS ruby laser worked!

    I think I have successfully made the DPSS ruby laser worked. Using 405nm high power laser diode, and small ruby (3.5mm diameter and 5mm long), the ruby lased. The following pictures show the result. (the left small red point) The following is the spectrum figure.

    Today, I get the 607nm lase successfully!

    I think raman shipfting is impossible. I cannot find reports about it.

    I am making this just for fun. I plan to lase the device at orange color (604 or 607nm) but I cannot find appropriate OC mirrors.

    I think the following picture should help. I do modulate the blue laser because when supply current rises, the output wavelength will shift from 445 to 450 nm. Modulation would avoid this condition. I think if you use more pumped power, the crystal holder could need water cooled but I am not...

    The crystal is mounted in a aluminum tray made by my self. Its diameter is 20 mm, with 6 mm thick. fixed by a screw column. Looking like the picture: The tray will mounted on the holder.

    Because all the materials are paid by my self, so the cancave OCs are difficult to find and very expensive. I just buy a cheap cancave HR, and form V style cavity so I can use cheap flat mirros. I do not know where is the power meter but I think I could try to find one.

    Thank you very much. But the bad messege is I am in Beijing China. The shippment costs very high for international people, so thank you but perhaps it is impossible to send me the mirror. :(

    Sorry I do this at home, but if possible, I am going to borrow one. My boss is not interested in optical field, so I have no instruments about it. :)

    I think the wavelength might be 640nm for all mirror is stopped at 700nm, mirror HR is stopped at 650nm.

    Fcl is 50mm,Lf is 51mm,L2 is 5mm, Lcav1 is about 75-85mm, Lcav2 is 70-75mm, ROC of Ro is 100mm.

    The crystal is ordered from optogam.
