• Education in Theory & Practice

• Start-Up for DPSS Laser Development
The LASKIT®-500 is a multipurpose laser source aimed at education, research and testing. In fact, it is the most versatile DPSS laser kit on the market, featuring five modes of operation.
The following fundamentals of laser theory and practice can be investigated*:
• Stability regions of laser cavity
• Various transversal cavity modes (TEM₀₀ and higher)
• Optimum cavity configuration for TEM₀₀ mode
• Optimum output coupling
• Laser threshold and differential efficiency
• Passive Q-switching threshold phenomena, pulse forms, opti-mization for maximum output power and maximum output energy, shortest pulse conditions
• Internal frequency doubling in CW-operation
• External frequency doubling in Q-switched mode
• Fluorescence lifetime of the active medium
• Laser dynamics (relaxation oscilla-tions, Q-switching), dependence on active medium parameters; comparison between different ac-tive media (Nd:YAG and Nd:YVO₄)
*Suggestions only.
The LASKIT®-500 includes:
• Pump laser diode with Peltier cooler and attached pump optics
• Laser diode driver & thermoelectric controller LDD1-1T (optional: LPS1-2T, microprocessor-controlled)
• Laser crystal Nd:YAG (Nd:YVO₄ optional), with a heat sink
• Set of two laser cavity mirrors (flat/curved)
• Cr4+:YAG passive Q-switch, AR/AR coated
• KTP frequency doubler with special coatings, in a holder
• Mirror and crystal mounts (3 pieces)
• Optical bench
• Diode laser module (670 mm) for aligning the laser cavity, with holder
• Infrared-to-visible converter (model IR-VIS-15-B), Ø 15 mm, for aligning the IR laser and mode analysis (also suitable for high-power lasers)
• Ultrafast photo detector (model UPD-300-SP) with rise time <300 ps, spec-tral range 320 - 1100 nm, external power supply, suitable for observing the relaxation oscillations and pulse duration of the Q-switched mode
• CCD linear array (model CCD-2000M) with 2048 pixels, high sensitivity, driver electronics and power supply, suitable for laser beam analysis, M² measurements, autocorrelators, etc.
The laser crystal, the passive Q-switch and the KTP-doubler are mounted in special holders for fast and easy exchange, alignment and handling. Switching from one mode of operation to another (e.g. from CW to Q-switched, or from IR to frequency doubling) can be done in a minute.

• Active Q-Switching: Explore the superior alternative to the Pockels cell Q-switch: The EOD option implements an electro-optic deflector as the Q-switch. A high-speed driver is included. The low-voltage (<1 kV) short-pulse (<1 µs) design assures safe operation. Classical active Q-switching with a Pockels Cell is also available (PC option).
• Monolithic Cr4+:Nd3+:YAG MICROCHIP Laser: Generates high peak-power subnanosecond laser pulses at 1064 nm. The microchip laser needs no alignment be-cause the laser mirrors are deposited directly on the laser crystal faces. The laser chip runs immediately when pumped with the laser diode of the laser kit. Best suited as a research tool in nonlinear optics, micromachining, laser-matter interaction, etc.
