Short Wave Pass Dichroic Beamsplitters SWP
CVI Melles Griot
Short wave pass dichroic beamsplitters exhibit high transmission for a short wavelength band, high damage thresholds, and high reflectivity for a longer band of wavelengths.
- Fluorescence microscopy
- Optical parametric generation
- Custome-specified reflected and transmitted wavelengths
- To maximize efficiency, reflect 45° s-polarization and transmit 45° p-polarization
- Damage Threshold:
- cw; 1 MW/cm2 @ 1064 nm
- Pulsed: 10 J/cm2, 20 nsec, 20 Hz @ 1064 nm
Concave Spherical Mirror Blanks
CVI Melles Griot
The SMCC plano-concave mirror substrates are polished to a 10-5, λ/10 surface on both sides (20-10 for SMCC-CFIR series) so the SMCC mirrors can be used as high reflectors, dichroic mirrors, or partial reflecting output couplers.
- Largest selection of sizes and curvatures to accommodate almost any laser resonator design
- Substrate Material:
- N-BK7 glass
- UV-grade fused silica
- IR-grade CaF2
Femtosecond Beamsplitters 400nm-800nm FABS
CVI Melles Griot
Femtosecond autocorrelator beamsplitters are broadband, 50% all-dielectric beamsplitters. They are useful in many types of pump-probe.
- Standard wavelengths of 400 nm and 800 nm
- Polarization Specify s- or p-polarization.
- Substrate material: VUV grade MgF2
- High reflector, metal and partial reflector coatings available
Plane Mirror Blanks
CVI Melles Griot
Serie PM: Plane Mirror Blanks
- Substrate material: UV grade fused silica, BK7, Zerodur and silicon
- High reflector, metal and partial reflector coatings available
Low-Dispersion Polarizers 400-800nm TFPK
CVI Melles Griot
The TFPK serie is low-dispersion polarizing beamsplitters to satisfy requirements for very-high-power, short-pulse lasers. These optics are ideal for intracavity use in femtosecond regenerative amplifiers. The main emphasis is on linear phase characteristics.
- Ideal for intracavity use in femtosecond regenerative amplifiers
- Low group-velocity dispersion for ultrashort femtosecond applications
- Custom wavelengths from 250–1550
- Substrate material: UV grade fused silica or BK7 glass
- High reflector, metal and partial reflector coatings available
Spherical Concave Mirror Blanks
CVI Melles Griot
The SMCX plano-convex mirror substrates are available in N-BK7, fused silica and UV-grade MgF 2. Polished to a 10-5, λ/10 surface on both sides (20-10 for SMCX-MF) they can be used as high reflectors, dichroic mirrors, or partial reflecting output couplers.
- Substrate material: UV grade fused silica or BK7
Ultrafast Isosceles Brewster prisms IB
CVI Melles Griot
Isosceles Brewster angle prisms are designed specifically for intracavity laser applications, usually for specific wavelengths or wavelength ranges. The dispersion of these prisms is less than that of an equilaterial prism, but the beam enters and exits the prism near Brewster's angle, minimizing intracavity losses.
- GVD correction prisms for femtosecond systems
- Two sides (AB) optically polished
- Extremely small loss for p-polarized beam
- Damage Threshold:
- Suprasil 1: 15 J/cm2, 20 nsec, 20 Hz @ 1064 nm
- Fused Silica: 15 J/cm2, 20 nsec, 20 Hz @ 1064 nm
- Optical Material: Suprasil 1, UV-grade fused silica or N-SF10 glass
