Featured inquiry:
We have a Millennia Pro 5sJ that is having LBO/Oven problems (the diodes are
fine!) which we're considering trading in for a newer laser. We use
the 5sJ to pump a home built Ti:Sapph oscillator. We only need 5W max. If you
could suggest and quote me on the appropriate product from you catalog I'd
greatly appreciate it. Please include any academic discounts and trade in value
for the Millennia Pro 5sJ.

Del Mar Photonics offers High Power CW 532 nm DPSS DMP LH series Lasers suitable for Ti:Sapphire laser pumping
 |
Features • Compact laser head with sealed enclosure for long lifetime • Long lifetime diode pack fiber-coupled to laser head • Excellent long-term power stability <0.5% rms over 24 hours • Closed-loop, purpose-built TEC chiller integrated in power supply (no need to buy a separate chiller to cool Ti:Sapphire crystal!) • 5, 6, 8 and 10 W versions |
DPSS DMP LH series is a compact, diode-pumped solid-state (DPSS) laser providing high-power, continuous-wave (CW) power at 532nm in a near- perfect TEMoo mode with extremely low optical noise and excellent long-term stability. DPSS DMP LH series is truly a next-generation laser designed and manufactured using many years of experience to provide a sealed, turn-key source of collimated green light with high spectral purity.
A number of key technologies guarantee this performance. Sealed technology keeps all dirt, dust and moisture out of the laser head to provide years of uninterrupted usage without need for cleaning or maintenance. All cavity optics is permanently locked in perfect alignment.
The laser head is a monolithic 3-dimensional design for ruggedness and compactness to minimize the space consumed in your lab or instrument. The fiber-coupled pump diode package, contained in the power supply, has an expected lifetime of more than 20,000 hours to minimize cost-of-ownership. The power supply also contains an integrated thermo-electrically-cooled (TEC) chiller. The chiller is designed specifically for this application to provide increased reliability and reduced overall system footprint. Additional features include automatic laser power control and USB/RS-232 interface for external monitoring and control.
DPSS DMP LH series is a state-of-the-art laser designed for today’s applications.
It combines superb performance and tremendous value for today’s
market.
