I'm about to order one of these. I have access to an Ocean Optics spectrometer at work so I will take some wavelength measurements

I'll have to get back to you on that... not too familiar with the absorption spectrum of nickel and copper

This system makes everything super easy, literally bolt on the harmonic generator and press a button on the controller for automatic phase matching. I'm well aware of the hazards of these short wavelengths. Most of the projects our company works on involve lasers so we're all very well trained...

In this system, 5th harmonic requires the mixing of the 2nd and 4th harmonics

3rd harmonic is in for testing!

3rd harmonic generator is on its way! They're sending us a loaner

Just took delivery of this bad boy today 😁. Quantel Q-Smart 850 Some of the specs: 850mJ/pulse @ 1064nm 430mJ/pulse @ 532nm 100mJ/pulse @ 266nm 213nm/pulse @ 213nm 5ns pulse duration, 10Hz rep rate, 0.5mrad divergence, 9mm beam diameter

For future reference, registration for the exhibition hall is free. The $895/$955 is for the SPIE conference. I attend the conference every year for work and the exhibition hall is any laser nerd's wet dream!

Subscribed for updates!!

Bump for information about where we can find this diode!!

Yea I'm not trying to break any efficiency records or anything.. just looking to learn a bit :p Thanks for the info!

Is it really as simple as placing the KTP crystal in front of the 1064nm beam? I don't have too much experience with DPSS lasers. Does the crystal need to be actively cooled?

Hmm I did find this: Witcore KTP Crystal 9x9x3mm Theta 90 PHI 23 3 S1 AR 1064nm S2 AR 532nm SHG Laser | eBay I wonder if the KTP will be able to handle the high pulse energy though.. this isn't a CW laser

Would you happen to know a source? :D

Nope, it was purchased for a project at work haha

Just got this bad boy in at work. It's a NuFern Fiber laser.. 10W average power, 5kW peak power, Q-switched, 100kHz pulse repetition rate, 100ns pulse width. It's fitted with a 7mm beam expander to give it <0.5 mRad divergence. Just need to select an objective lens now! Can't wait to see what...

Yea that's what I figured. I did find a CNI 7W module for $6200 though. We may push into the 808nm range.. way easier to get a ton of power out of NIR. Thanks anyway! Ideally we would need to be as close to CW as possible for our technique - but I will look into pulsing a lower power source...

Yea I'm having a hard time finding anything else. I contacted CNI and they make an OEM module with fiber output for around $6500. This is for an experimental skin treatment device we are developing. We'd like a max of 400um, although the design can be modified to accomadate something larger.

Can someone point me towards a company that offers a fiber coupled 10W+ 630-660nm laser? Budget is <$5000. I've seen IPG Photonic's Red raman fiber laser but looking to see if there's anything else out there. Thanks in advance!

I've never actually used this one before though :p For the most part, I stick with our Thorlabs LPM with its glorious 1nW resolution (5W max)
