Buying Red Lasers

SHIPS TODAY: AeroDIODE offers fiber-coupled laser diodes at 635 nm and 660 nm as stock items or associated with a CW laser diode driver or pulsed laser diode driver. They are compatible with our high speed nanosecond pulsed drivers. The single mode laser diodes (Fabry–Pérot laser diode ) can reach high power in nanosecond pulse regime up to 50 mW. Most turn-key diode & driver solutions are optimized for single-shot to CW performances with pulse width lengths down to 1 ns. The laser diode precision pulses are generated internally by an on-board pulse generator, or on demand from an external TTL signal.

TOPTICA offers a large variety of wavelength-selected single-mode laser diodes. Among more standard laser diodes you will also find "rarities", i.e. diodes with output wavelengths that only TOPTICA provides. The diodes can be purchased separately. In addition TOPTICA can integrate any diode from the stock lists into a tunable diode laser system: Fabry–Pérot or AR-coated laser diodes may be integrated into a diode laser systems, DFB/DBR laser diodes into a DFB pro and Tapered Amplifier into an TA system.

Each type of diode is carefully tested in an external cavity laser configuration with respect to coarse tuning range, mode-hop-free tuning range and power limits. The results are disclosed on request to the customer in a detailed datasheet. In case you can still not match your wavelength of choice, contact TOPTICA – and chances are very high that we can provide it within very short time.

The lasers you need. From the people you trust. Our experience, your advantage.

Red fiber lasers were the earliest models developed for the cutting-edge microscopy platforms built in the laboratories of Dr. Stefan Hell, and flow cytometry platforms tested in the lab of Dr. William Telford of the Core Flow Cytometry Facility at N.I.H. where beam quality, reliability, and stability continue to be of the utmost importance.

Wavelengths from 620 nm to 775 nm are available in either an OEM compact package, and/or a 2RU rack mountable package with integrated power supply and are equipped with a user-friendly graphical user interface for ease of setup and operation. MPB offers an optional fiber coupling service which provides the user up to 1 watt out of the fiber.

Applications where MPBC red lasers are used include microscopy, genomics, optogenetics, DNA/RNA sequencing etc.
