    589nm vs. 594nm Yellow Wavelength Comparison

    Very cheap to buy new dye for 594nm https://www.ebay.com/itm/203242241966?hash=item2f522e7fae:g:aWcAAOSw6vpf9~wq For me, dye is too wide of an output spectra.

    Combining two NUBM36 with a PBS cube or by knife-edging prism method

    Thank you for your hard work and sharing the results my friend. I may copy you, but try to put 4 arrays together.

    589nm vs. 594nm Yellow Wavelength Comparison

    I chatted with Lasence, because on Alibaba they have a dozen listings for 575nm lasers, but in the conversation they said due to customer complaints about power stability. I remember in this thread people mentioned the humidity stability issues of the doubler crystal(S).

    589nm vs. 594nm Yellow Wavelength Comparison

    Do you have advice on sourcing a low mW output 575nm laser my friend? I have a 571nm, and it looks dirty green to me rather than yellow.

    Success shifting wavelengths of single mode 660nm diode laser using diffraction grating method

    Our RnD facility is in El Segundo CA, and we live in Manhattan beach CA. It would be an honor to have Singlemode visit us anytime! I will give him a ride in a Tesla Plaid Model S that will blow his mind. I would love his help setting up an array of very narrow spectrum observing spectrometers...

    Success shifting wavelengths of single mode 660nm diode laser using diffraction grating method

    A few folks here mentioned to me shifting a laser output wavelength with a diffraction grating. It seemed too amazing to be possible, but it works! The magic is getting a setup reflecting a portion of the gratings reflection right back down the laser diode. Able to shift this 660nm single...

    rare diodes with special green/blue wavelength

    I'm very interested in these diodes if you still have any my friend.

    New 3 x Piooner 16x Blu-ray drives

    Lots of power in a single mode diode. Good luck with the extractions!

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    The cup and insulation wadding was added because condensation and frost formed faster and harder than I expected for how dry of a day it was. I gotta see how to shrink the spectrometer plots, because I took streaming data logs of sweeping the temperature vs wavelengths between a couple of...

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    The dominant energy wavelength (in the multi-mode spectra) was 375nm, and it remained stable across a wide temperature range.

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    Nice paper and nice experiment Singlemode. I've got a few diodes in the 460-495nm range to measure nm/degC drift and share results when I get a few hour. Do you understand how the 375nm multi-mode LD had no shifting with temperature from -20degC to 60degC, aside from getting dim at 60degC and...

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    I am so grateful for you sharing this information Singlemode. 25 wavelengths of blue to green transition for $10k in diodes is a lot, but also priceless for experiments if they offer any output level with a stable-ish single mode or at least repeatable double mode power level. I would mount...

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    Your adhesive will set something like 1/2 the cure time for every 10-15degC hotter it's sitting at during cure. Drive a small reverse TEC current and it should setup a lot sooner.

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    It's definitely the IR not the mean path, my chambers can pump down below 1micronHg, and the surfaces are surface insulated. I have a IR heat flux sensor to be able to easily quantify it. It's what lead me to multiple layers of gold foil separated by a polyethylene mesh scrim. This is because...

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    You may find you get a higher total deltaT by using 2 stages of TEC over 3 stages of TEC, and not get your box as hot. This is because of each series stage of junctions being a higher heat load than your diode. You may also get your last 2nm by adding IR shielding around the LD cold platform...

    Building a orange (613nm) Laser from scratch with off-the-shelf parts (and for cheap!)

    Nice job on protecting from humidity. I like the idea any diode you mount in that housing let's you shift the wavelength by a significant amount. How useful to be able to stimulate a sample with a single frequency LD, then shift the input frequency both directions by +-5nm and re-capture the...

    Sharp 395nm 300mW Diode GH0393AA2G

    The short wavelengths can show Raman lines very nicely. Remember the bright PL emissions are always in the same wavelength range. This means short wavelength pumps give you the most clear Raman wave numbers when the shift is smaller and more near to the pump. Sometimes 785nm gives you <1% of the...

    Sharp 395nm 300mW Diode GH0393AA2G

    I have a 375nm 200mW that my eyes at least vividly see (like 1-2mW of 532nm perhaps). I would guess 395nm will appear bright on most bright colored surfaces from stokes shifting dye emissions. Im just using them for measuring Raman shift wavenumbers and PL emissions spectra measurements, so if...

    I'm happy to take 3 of them to help you get enough orders in. I can pay you in advance as usual.
