Dear Listers, is there a single or multiple Economical source/s for the diode laser lines 405, 488, 561 and 647 nm lasers with higher total output power 100-1000 mW. Thanking you in advance Shiv Microscopy Facility Manager 8, Institute for Genomic Biology University of Illinois at Urbana-Champaign 1206 West Gregory Dr. Urbana, IL 61801 USA Office: 217.333.1214 Fax: 217.244.2496 [hidden email] http://core.igb.uiuc.edu |

Diode lasers can mostly meet those power requirements these days; the problem is the 'economical' part.
There are so-called 'white' lasers that can reach all those wavelength ranges, but after you slice out the part of the spectrum you want to use you probably won't have 100mW left. It's a tricky problem! Really the only way I know of to meet these parameters off-hand is to just buy the individual lasers, but you're looking at ~$10k each on average for these lines, possibly more.

Hi, You could check out the solid state lasers from Cobolt (www.cobolt.se): up to 100 mW for 491 nm, up to
75 mW for 561 nm. They are much less expensive compared to other manufacturers
(e.g. CrystaLaser), at least in Europe two years ago when we purchased two of
them. We use them in a widefield set-up for single particle tracking. I have never heard of a 647 nm diode laser, though. There are 636
– 640 nm diode lasers, but as far as I know they are limited to about 30
mW. I would be interested if someone knows of more powerful solid state lasers
in this wavelength range. Best regards, Kevin Van: Confocal

Dear All, No commercial interest at all, but in
response to the discussion on diode lasers, I have just noticed that there is a
642nm diode from Opnext, the Opnext HL6385DG. The blurb from optics.org follows: The
Opnext HL6385DG is a single longitudinal mode, low aspect ratio laser diode
with optical output power of 150mW CW (typ), at a lasing wavelength of 642nm,
operating current of 280mA, threshold current of 110mA, operating voltage of
2.6V and LD reverse voltage of 2V. The operating temperature range is -10
degrees C to +40 degrees C. Supplied
in a 5.6mm package with LD-only pin configuration, this is a single
longitudinal mode laser diode with TE mode oscillation. The 5.6mm package size
is particularly suited to small, energy-efficient displays and low-power,
high-quality optical applications. Download
specifications from Photonic Products’ website: How well this would suit I have no idea. Opnext website is www.opnext.com All the best Darran Clements Babworth: Insight and Analysis for the Internet, Communications and

Dear List,
Shiv just mentioned Cobalt lasers. So I thought I would use this opportunity to give this company some well deserved praise.
Awhile ago I decided to replace our aging Argon ion laser on our MRC-1000/1024 system. I ordered a Cobalt “Dual Calypso” Solid state laser that gives two lines 491nm and 532nm each line 20mW. After receiving the laser I needed to build a heat sink and order new dichroics etc. So the process took me awhile. When finally I had finished incorporating the laser into our home built laser combiner, I noticed there were some fluctuations in the laser intensity.
After a couple of quick emails to the company describing the problem, they sent out a data cable by post. When this arrived it was a simple matter to plug the laser power supply into a computer with network access. They were then able to gain remote access to the laser and an engineer conducted a full diagnostic and service remotely, and solved the problem!
It appeared that our heat sink was too efficient, and the laser could not reach it set temperature points. They increased the power output of the laser to 25 + 25mW and adjusted three separate temperature controller set points and the laser has performed beautifully ever since. That was really impressive service, and I certainly would recommend Cobalt.
No commercial interest in Cobalt.
